Algebra 2 Absolute Value Functions

Algebra 2 Absolute Value FunctionsAlgebra 2 has a number of very useful and interesting functions that can be applied to solve all sorts of problems. It is always important to understand all the features that the functions offer, before we can use them correctly. The following explanation of some of the most common mathematical functions and their applications can be helpful in helping you find your way around algebraic equations and graphs more effectively.Let us start with the functional derivative. A function is said to be a derivative of a second term in an equation if and only if the derivative of the first term is equal to the derivative of the second term. In algebraic terms, this is called a power function. Algebra 2 has one very important functional derivative - The absolute value function.The absolute value function is given by x2 + y2 = z2, where x and y are two numbers, and it is a third number. This function tells us that x and y must be negative so that they will cancel each other and no change in the value of x or y will result.The absolute value function is useful when you need to know the absolute value of a number, or even any number in general. This can often be calculated using the Taylor expansion.The derivatives can be used in algebra to describe what happens to something as it moves from one point to another. For example, the linear approximation to the tangent of a line is given by tan(x) = x/a. The tangent of a line is the distance from a point on the line at a certain angle to the line itself.Derivatives are really helpful when you are solving algebraic equations. The derivatives tell you whether the function is increasing or decreasing, and sometimes they can also tell you what the direction of the function is. The derivatives of sin and cos form a good example of the application of the derivatives.Algebraic equations are usually written in algebraic notation, in which case derivatives can be described using a sequence of symbols. The derivative of x2 equals a minus b (where b is a constant), where x2 is the constant, and b is the derivative. The derivative of a trigonometric function is a vector quantity which can be represented as the sum of three numbers. When using algebraic functions for algebra, it is important to realise that, in most cases, a different function can be used for the derivatives than the functions that are used for the equation.

High Notes High Fashions What to Wear to Your Next Audition

High Notes High Fashions What to Wear to Your Next Audition Sign up successful This is a topic that many students don’t ask their voice teachers  about because, let’s face it, in a 45- to 60-minute lesson there is a lot to cover! On the day of an audition there is a lot to think about, such as your song choice, dealing with nerves, remembering to bring specific materials (headshot and resume), hoping the pianist plays your piece to your liking, memory issues, and, of course, how you look and feel. Having one or two “go to” audition outfits lets you have one less thing to think about on the day you have that really important audition. Looking and feeling great is just an added bonus to having a successful audition! Here are some helpful tips on choosing what to wear to an audition Tips for Women • Cinderella is proof that a pair of shoes can change your life Well, a pair of shoes can make or break your audition! Make sure your feet feel comfortable and that you can sing comfortably. Keep in mind that adding four-inch heels can change vocal posture. Be sure to practice in your shoes before your audition! • Say Yes to the Dress! When choosing a dress, make sure you feel comfortable enough to sing in it and you have plenty of room to breathe! It is a good idea when buying a dress to breathe deeply in the dressing room before you buy it, and also make sure it complements your body type. Black is always in style and is slimming to every body type. Things to avoid include large prints and extremely bright colors (which can distract a judge), and a dress that is either too tight or too short. • I wear the pants For those who sing operatic mezzo roles, consider a classic blazer, solid-colored dressy blouse, and black slacks. When wearing this type of audition outfit make sure your pants are ironed and/or dry cleaned to avoid wrinkles or looking messy. •  Good hair day:  Please keep your hair off your face! There is nothing worse than watching someone brush their hair away from their face constantly during a song. Great options include wearing your hair half up, a bun, or a fancy ponytail. • Maybe it’s Maybelline Makeup is just another part of putting a look together. When applying makeup for an audition, make sure it is natural and that you still look like your headshot picture! • Put a ring on it: Jewelry is a personal choice and statement. If you choose to wear jewelry with your outfit, make sure, again, you feel comfortable in it. Also remember that less is more.  Things to avoid include jewelry that feels heavy on the neck or ears, long dangling earrings, very sparkly necklaces, and earrings that could distract the judge. If youre wearing bracelets, avoid ones that have charms that make noise. You want the judge to be focusing on the beauty of your voice, not your bling! Tips for Men • Check your fly: When choosing a suit, make sure it is tailored to your body type! Choose a dress shirt and/or tie that complements the color of the suit. If youre wearing a three-piece suit, make sure the vest and pants have plenty of room so you feel comfortable enough to sing and breathe! If you have gained or lost weight make sure to take your suit in for the appropriate alterations. • Dressy/casual: Not wearing a suit? A great pair of jeans, dress shirt, and tie are sometimes all you need! Just make sure the jeans are in great condition jeans with holes look sloppy and unprofessional,  and could potentially give an air of not caring about the audition. • Shoes are a girl thing: Though this may be true, a pair of great dress shoes can really complement a suit. Be sure the shoes are not too tight and are comfortable to stand and sing in! There is nothing worse then putting on shoes that are too tight. When wearing dress shoes make sure to wear a nice dress sock that is pulled up. Happy shopping happy singing! Chelsea F. teaches singing, piano, and music theory in New York, NY.

How to Change Those Guitar Strings.

How to Change Those Guitar Strings. Change your Guitar Strings in Six Easy Steps. ChaptersSelecting New Guitar StringsDifferent Signs that It’s Time to Change your Guitar StringsA Step-by-Step Guide to Changing Your Guitar StringsBeing a musician means always hitting the right notes to achieve the sound and tone that you want.Of course, it requires work to achieve your desired sound all of the time, and it also requires that your instrument be properly maintained and tuned. The strings on your guitar are a good place to start - because, really, it's these things that are making the sound.This, obviously, applies to acoustic guitar players as much as electric bass players. And, within the kingdom of acoustic guitars, it applies as much to the orchestral as it does to the dreadnought. It applies to the mandolin and banjo strings too.When you are a professional musician, you'll know this - but too many beginner guitarists think that it is something that they needn't worry about.In fact, they do. Because you're not going to get the best guitar sound you can get, nor the best playability, if you're guitar strings are dirty, rusty, or old.However, if you're a beginner, you might not know what you're doing. When do you need to change your guitar strings? you ask, How do you know if a string needs changing?Are there guitar tutorials for changing your strings?  How do you change the whole set of strings on your guitar before playing guitar?So many questions. We’ll answer all of them - and walk you through the steps you need to take in the article below.Once your strings are on the point of fraying, they’re all used up, or they constantly need re-tuning and tightening whenever you play guitar, it’s time to replace them.Here's your method for changing your guitar strings.But do you know what your guitar strings are really made of?  What are the different types of guitar strings?  Do you know how to choose the right kind of string for your guitar?When you go into a guitar shop, the options can be pretty overwhelming. What is phosphor bronze, Eli xir, Dunlop, or Slinky? What's the difference between classical guitar strings and acoustic guitar strings? Do you want Nanoweb, Rotosound, or Planet Waves? Dr Strings or Dean Markley? Do you want long life strings, or bronze alloy?There is a lot to choose from.The Type of StringStrings are characterized by their windings - that is, by the way that the metal is actually wound around the string’s core.There are three kinds of winding:Round wound - this is the most popular type of strings today, as they produce a brighter sound and have more grip.Semi-round strings - this type of string is softer to touch and produces a warm sound.Flat wound strings - these strings have a very smooth surface texture and a warm, vintage sound. These strings are very popular with jazz and acoustic music.As a beginner guitarist, you are probably only going to be interested in round wound strings - and brands like Elixir strings, Ernie Ball strings, and the majority of nylon guitar strings sets all fall into this category. It is very unlikely that you would want flatwound strings at this point.Guitar String MaterialsEach type of guitar has its own type of guitar string, and it’s important to make sure that you do not put nylon strings meant for a classical guitar on an electric guitar, or vice versa. Of course there is a difference between electric guitar strings, bass guitar strings, acoustic strings, and nylon string. They all have their specific purposes and shouldn't really be mixed up.Knowing your strings is essential for any budding guitarist, and something that should be covered in guitar classes or during your first couple of private lessons - no matter which stringed instruments you might be playing.If you are taking your guitar everywhere, you might have to change the strings more often.All kinds of strings in order to play well on the guitar. Different materials bring different sounds to your guitar.If you want to know everything there is to know about guitar, you sho uld know that there are different types of guitar strings which can be categorized according to their material and their use. This is essential knowledge for the guitar player.Stainless steel strings make an impact, are louder, and are very precise. However they will wear out your frets quickly!Nickel-plated steel strings â€" these have almost all the same benefits as stainless steel strings, but are a bit softer and less clear.Nickel strings â€" this metal isn’t very strong on its own, so it is often mixed with steel to create an alloy. Nickel strings give you a warm, round sound, but are a bit less precise than stainless steel.Nylon strings â€" made especially for classical and traditional guitars. Make sure that you know which type is for you â€" each manufacturer has their own slightly different style of nylon strings, designed for flamenco or straight classical.Silk and steel â€" these strings are made especially for folk guitars. These have a soft and delicate tone, and are perfect for playing harmonies.Bronze strings â€" for folk and electro-acoustic guitars. These strings produce a warm and fairly well-balanced sound â€" bring on the arpeggios!Tightening Your Strings: String Gauge - or String Sizes.The tension of a string should correspond to its gauge - and to the material of which it is made. Steel guitar strings - so those for acoustic, acoustic electric, and electric - will require much more tension than those for a nylon string guitar. If you put electric guitar strings or bass strings on a classical, the guitar neck will just snap.String gauges are often described as extra light, medium, heavy, or as a decimal figure that represents the diameter of the strings (.014 or .059 for example). The lower the number, the finer the string.The tension of your strings will help define the sound and the kind of feel that you have.Traditional gauges range from extra light to heavy, and though the differences may seem bewildering to a beginner, choosing the right strings can transform your playing.The higher the gauge, the thicker the string, and the higher the tension will be when the string is tightened. Essentially, strings with high gauges could hurt your fingers and make it difficult to play, especially for beginners. It makes the strings more difficult to press to the fretboard.Low gauges won’t hurt your fingers as much and will make it easier to play (perfect for students working on their finger vibrato), but they will make it more difficult to play certain techniques.Generally, beginners should start with lower-gauge strings as they develop their fingers and explore different musical styles.Watch out changing gauges on your guitar, however, because it can affect the intonation of your instrument.Different Signs that It’s Time to Change your Guitar StringsWhen do you need to change your guitar strings? How can you tell when they’re damaged or used up?Here are some of the different signs:A broken string â€" Obviously, in th is case, you need to replace the string in order to keep playing guitar. It’s nothing to worry about, because a broken string is fairly normal, but if it happens to you a lot, you probably need to get your guitar checked to make sure that there aren’t any problems. Tightening your strings too much or too little can also damage them and cause frequent breakages. Take your guitar to a specialist luthier if you are experiencing problems.Oxidized string â€" Oxidization will occur on all metal strings, even on heavy gauges and acoustic guitars. If you’re sweating a lot as you play, that will also contribute to the oxidization. Some brands do anti-corrosive strings - such as Elixir Nanoweb - so that the string set doesn't oxidise so quickly.The sound just isn’t the same â€" often a new string will have a bright, clear, tone that quickly disappears as it’s played. Over time, the sound will become more muted and the notes cut abruptly as the strings vibrate less. If this happens, it’s time to change your strings. You'll notice this more on an acoustic guitar string than on an electric - because you don't have the amplification!You’re hitting the wrong notes â€" you’ve maintained your guitar, tuned it and adjusted everything, but it just doesn’t sound right. Some strings will loosen faster than others, which is why some notes sound wrong, but others are still okay. Guitar tuners can help with this in the short term, but get yourself to a shop that sells acoustic and electric strings pronto.Your strings are poorly made â€" it’s a common problem with new guitars, and not just for those on the cheaper end of the spectrum. Manufacturers, particularly at the low end, tend to put cheap strings on their guitars to keep costs down. We’d recommend changing the original strings with some higher quality ones to get a better sound and style.Are your tab readings confused because of the sounds coming from your guitar?As you can see, there are many different re asons that you may need to change your strings and each guitarist will need to do so with a different frequency.Don’t let worry about changing your strings stop you from playing. While some guitarists change their strings every month, others may go a whole year between sets.A Step-by-Step Guide to Changing Your Guitar StringsChanging your guitar strings isn’t very difficult, but it can seem like a challenge, especially for novice guitarists. To change strings, what you'll need is a string winder, a guitar tuner, and a pack of new strings.It’s a basic skill that every guitarist must learn as soon as he picks up his first guitar and accessories.It’s a necessary skill for any regular guitarist!Here are the basic steps to change your guitar strings.Loosen the Strings and Remove Them from the BridgeThere are two different ways to do this, and they always cause debate â€" is it better to take your strings off one by one, or remove all of them at once and replace them all at the sa me time?Some people say that, if you change your strings all in one go, the change in tension on the neck can damage the guitar. Watch out too that during the string change you don't damage the soundboard or anything yourself.You just need a bit of motivation with your guitar!If you do decide to change all of your strings at once, it’s a good opportunity to properly clean your guitar, especially the frets, where sweat and dust tend to accumulate. Although, obviously, you can do this when you do it one at a time too.1/ Undo your StringsBegin by loosening the first string completely until it sag by turning your tuning nuts counterclockwise.Then you can cut the strings with a pair of pliers, or pull them out completely by totally loosening the tuning nuts and pulling the strings out from the holes of the bridge.2/ Redo the bridgeThe bridge of your guitar has little tips that look like black or white buttons and allow the strings to cling to the inside of the guitar.If possible, use a bridge remover to clean this area.3/ Clean your GuitarThis is your opportunity to really clean your guitar â€" make sure that you cover all of the bases including the neck, frets, and headstock.Don’t ever use shoe polish or a glass cleaner â€" they could damage your guitar.A simple cloth moistened with a bit of chamois or a microfiber cloth is all that you need.Change Your Strings4/ Prepare your StringsSome strings are color coded at the ends to tell you which note they should play and where they should go. Whilst you should be able to distinguish between the bass string and the light strings, the ones in the middle can get confused.5/ Put the New Strings onThe most common method is to start with the finest string, and then do the largest one, continuing to alternate from low to high gauges until they’re all on.This way, you can keep the tension consistent.Learn how to change your strings right here!Start by putting your strings through the hole in the bridge, and then fix it i mmediately.  It is important to keep some tension in the string while you perform this step.Try some different guitar chords  or check this out.Next, tighten all of the strings on the guitar, and then pick the next string you want to add. Check the color on the tip, and put it in the corresponding hole.Make sure that you always wrap the string to the right - it should always go clockwise.Put your string through the hole and pull, but always make sure to leave a bit of slack to wind around the tension key.  Don’t fully stretch your strings to the proper notes now; you need to finish restringing your guitar before you tune it.Repeat these steps for each string until your guitar is completely restrung.6/ Tune Your GuitarObviously, then, you need to retune it! But we're betting that you know how to do that by now!Remember that new strings tend to become out of tune much more quickly than older strings. So, you'll have to make sure you tune up regularly in the first couple of days afte r you change your strings!1 - Unwind your stringsUsing the tuning pegs, unwind the strings until loose - one at a time2 - Clean your guitarClean the space beneath the strings, as this accumulated dust affects the sound3 - Identify which string goes whereTake the correct string you need to replace each individual one you have removed4 - Put the new strings onWind up the string, again with the tuning peg, until it is firm. Do each string.5 - Tune up!At this point, make sure the guitar is back in tune!

Online Simplify Equations Tutors

Online Simplify Equations Tutors Equations are the very common and used in almost every sub-topic in math. Equations consist of one or more than one unknown variables with different coefficients and constant numbers. Exponent is the degree of the variable in the equation. The degree of the variable can be one or more than one. There are various mathematical operations which are used to simplify and solve equations. Example 1: Simplify and solve for x in the equation 9 x 4 = 50? Solution: Given equation is 9 x 4 = 50. Here the unknown variable which needs to be solved for is x. First step: Adding 4 on both sides of the given equation. (9 x 4) + 4 = 50 + 4. This gives 9 x = 54. Now dividing both sided of the equation by 9. This gives 9 x/ 9 = 54 / 9. This reduces the given equation to x = 6. Hence the solution is x = 6. Example 2: Simplify the equation 4 (x 3) + 5(x + 2) + 2? Solution: Given equation is 4 (x 3) + 5(x + 2) + 2. Here the variable is x; distributing the number in front of the braces. This gives 4 (x - 3) = 4x 12; 5 (x + 2) = 5x + 10. Combining the similar terms in the equation. This gives 4x 12 + 5x + 10 + 2 = 9x + 2 -2 = 9x Hence the simplified form of the equation is 9x.

Physics Glossary

Physics Glossary You Should Know These Physics Terms ChaptersNames of the Different Branches of Physics StudyPhysics TerminologyGeneral Physics VocabularyA part of the problem compounding students’ fears of physics is its vocabulary: those lofty scientists seem to speak a language all their own, with just a few words of English thrown in!With the rare exception of Stephen Hawking, who gave the world an explanation of the cosmos in everyday terms with his A Brief History of Time.But, really, the language of physics is not that hard to grasp if you know the key terms and word groupings.That is why your Superprof presents you with this physics glossary!Unlike a dictionary that might define a word but leave you no clearer on its meaning in a scientific context, we aim to put a bit of meat on each word’s bones so that you can truly sink your teeth in and get a good bite on the matter.Along the way, we’ll include a bit of extra information so you can see how each term fits within this discipline called physics.Get a physics maths tutor here.Einsteinian relativity â€" as opposed to Galilean relativity.The essence of modern physics deals with extremes: either very small particles or very large aspects or properties of matter; long distances or high speeds.The ‘middles’, as they are called, are usually addressed by classical physics.An apt way to describe this difference would be the behaviour of a gas. Studies conducted at 0 º Celsius might be a matter for the classical study but that same gas, at absolute zero â€" -273.15 º Celsius would be of interest to anyone conducting modern physics research.Absolute zero represents the total absence of heat; it is the lowest limit on the thermodynamic temperature scale.If you are an undergraduate majoring in physics, you wouldn't declare yourself a classical or modern physicist because modern physics depends heavily on classical theories.Unlike in music, where one could specialise in playing classical piano or modern jazz piano, one needn’t elect to practice classical physics or modern physics.However, as an aspiring physicist, you could choose a specific field of physics in which to apply yourself.Let’s examine some of them, now.Also, take a closer look at pioneering physicists and their discoveries!Physics TerminologyIf you are mad for The Big Bang Theory, you might aspire to follow in Sheldon’s footsteps to become a theoretical physicist:  that would call for you to use mathematical equations to predict the outcome of theories.However, if Leonard is your fav, you could emulate him by becoming an experimental physicist â€" the complement to your theoretical counterpart, you would conduct actual experiments and record your results.Raj is an astrophysicist, studying the nature of cosmic bodies rather than their position and how they move in space.Particle physics, also known as high energy physics involves the study of particles that make up matter and radiation. Note that particle, in this sense, could be anything from electrons to dust.Appl ied physics suggests you could help develop new technologies or help solve a thorny engineering problem regarding such development. Indeed, this branch of physics is the link between scientific study and engineering.Biophysics borrows methods of analysis used in physics to study any biological phenomenon.Atomic physics: you know those nifty diagrams of shells and valences and electrons in your science books? They were conceived by atomic physicians, who study the composition and structure of atoms.There is a difference between atomic physics and nuclear physics in spite of the synonymous usage in English of the words  atomic and nuclear.Nuclear physics concerns itself solely with the nucleus of an atom. Have you ever had an MRI? It and other facets of nuclear medicine such as PET scans and other spectroscopy came about through discoveries in nuclear physics!Condensed matter physics involves studying the behaviour of solids and liquids using various physical laws.This field of resear ch is a crossroads where several disciplines meet: theoretical physics, particle physics and nanotechnology blend with chemistry and all of the areas formerly known as solid state physics.It is also one of the most active fields of study in contemporary physics because of its sheer breadth and diversity of materials to study.This is generally not the image that comes to mind when a physicist thinks of quarks! Source: Pixabay Credit: RitaEGeneral Physics VocabularyNow that we’ve looked at some physics specialities you might consider for your career, let’s drill down to the verbiage used by this discipline â€" some of which might even sound familiar to you!Quark: you might know this word as the name of a dairy product but, in physics, it represents an elementary particle.However, to make matters more confusing (physical) quarks come in 6 flavours: up, down, top, bottom, charm and strange. Dairy quark is generally unflavoured!Look up for a physics maths tutor now.Quarks always feat ure in configurations of three: one up/two down; two top/one bottom and so on.A hadron is two or more quarks held together by the strong force.Any time you hear hadron, boson or fermion, you now know those names represent classes of subatomic particles.Ever heard of a hadron collider? Now you know what it was named after!A neutrino is not the hippest neutron in the atom; it is a subatomic particle with no electrical charge and very small mass. It travels very quickly; close to the speed of light!Quantum: this word is used a lot in physics, from describing discrete fields of study (quantum chromodynamics) to delineating entire branches of physics, such as quantum field theory.Used by itself, quantum represents the smallest possible unit anything can be divided into: at the quantum level, e.g.An isotope is a possible form of an element. Two or more elements may have the same number of protons but vary in the number of neutrons in the nucleus.Perhaps the most renown of such elements is uranium-235, which differs from uranium-238 because it has 3 fewer neutrons, even though they are both the element identified as uranium. (Uranium-235 is used in nuclear power stations and to make nuclear weapons).We tend to think of waves as something the ocean generates or something we do with our hands, but physicists associate waves with any disturbance that transfers energy through matter or space.Waves can be either a vibration or an oscillation, of a physical medium or of a field, around essentially fixed locations.

Skype English Classes for Schools Ching Man Chan

Skype English Classes for Schools Ching Man Chan Skype English Classes For SchoolsMoving from Shenzhen, China, a bustling, industrial city of 7 million people to the quaint countryside of Helena, Montana, has been an adjustment in many ways for 16-year-old Ching. “He’s a bright, respectful, and motivated student,” says Ann, his online English teacher. Ann taught Ching daily English classes through LOI English from April to June. In that time, “quite simply, it seems that Ching learned more English in two months with Ann than the prior 11 months he was in the US” says Therese, Ching’s supervising teacher at Helena High School.How were the Skype English Classes For schools?The topics of these daily online English lessons were aligned with Ching’s grade level and subjects he saw during his regular academic classes. The goal was to ease Ching into participating in regular classroom discussions. It was Ann’s role to be a facilitator, mentor, motivator, collaborator, and language partner, with whom Ching could practice th e language he’d already been exposed to and acquire new grammar, vocabulary, and confidence.The lessons always began with general conversation. “This is probably the most important part of the lesson. Through conversation, Ching began to learn relevant vocabulary, gain a better understanding of what was going on at school, and most importantly, gain confidence” Ann says. It was obvious he was motivated, but just needed more comprehension of vocabulary.  For example, he really wanted to improve his basketball skills, but said he didn’t understand things sometimes at practice. So, they would spend this portion of the lesson discussing basketball vocabulary, rules, and plays. “This is where having the internet at our fingertips really helped. Once, the conversation led to Ching saying he didn’t know the position names. So, we watched a short video demonstration of the positions. By the end of the conversation, Ching was talking about which position he might be able to play , describing his strengths and weaknesses and his plan to improve.” Other times, Ching would bring questions about his assignments or things people had said to him. They would discuss what questions his assignments were asking and work through vocabulary until Ching was prepared to do his homework independently. “Once, the conversation even lead to us googling types of cafeteria food. Another time, we googled and discussed the right man bun styles for Ching! These topics were all relevant to Ching’s life, so he could apply what he’d learned each day.”How Did Skype English Classes For Schools Integrate Subjects?Each lesson involved reading, listening, and a grammar focus. As they worked through the material together, Ching often asked questions, and they could build his understanding by finding using the internet to find supporting information, pictures of vocabulary, or videos to support Ching’s comprehension. “The one-on-one lessons, plus having the internet readily a vailable made Ching’s comprehension much stronger” says Ann.Skype English Classes For Schools Results?When Ching began, his official English level was pre-intermediate, which means he could speak simple conversational English with some hesitancy. He used simple and compound sentences, and didn’t understand questions at times. He had difficulty recalling advanced vocabulary words. His response to questions was often, “I don’t know, maybe.” By the time his final exam came around, he was able to speak for 3-5 minutes on his own about his opinions and make comparisons. He had much better listening comprehension, and he began to use correct grammar tenses in speakingâ€"which is especially hard for Chinese students, because the Chinese language doesn’t have any verb conjugations! He still has work to do, but he is well on his way to improving not only his grades and English skills, but becoming a part of his community, adapting to his new life in Helena, and maybe even growi ng a man bun.
