# Topic: Quotient rule

 Quotient - Wikipedia, the free encyclopedia For example, in the problem 6 ÷ 3, the quotient would be 2, while 6 would be called the dividend, and 3 the divisor. In more abstract branches of mathematics, the word quotient is often used to describe sets, spaces, or algebraic structures whose elements are the equivalence classes of some equivalence relation on another set, space, or algebraic structure. Quotients also come up in certain tests, like the IQ test, which stands for intelligence quotient. en.wikipedia.org /wiki/Quotient   (211 words)

 Quotient rule - Wikipedia, the free encyclopedia In calculus, the quotient rule is a method of finding the derivative of a function that is the quotient of two other functions for which derivatives exist. Students of multivariable calculus will recognize it as one of the chain rules for functions of multiple variables. Another variation to this mnemonic is given when the quotient is written with the numerator as Hi the denominator as Ho: "Ho-dee-Hi minus Hi-dee-Ho over Ho-Ho." en.wikipedia.org /wiki/Quotient_rule   (453 words)

 PlanetMath: quotient rule The quotient rule says that the derivative of the quotient The Quotient Rule and the other differentiation formulas allow us to compute the derivative of any rational function. This is version 10 of quotient rule, born on 2002-05-17, modified 2002-05-18. planetmath.org /encyclopedia/QuotientRule.html   (66 words)

 Quotient Rule We must be a little careful in determining the domain of the quotient f/g: a real number x lies in the domain of f/g if and only if it is in the domain of both f and g AND g(x) is not equal to zero. The domain of the reciprocal is the set of all points x in the domain of g for which g(x) is not zero. The quotient rule says that the derivative of the quotient is "the derivative of the top times the bottom, minus the top times the derivative of the bottom, all divided by the bottom squared".....At least, that's one way to remember it. oregonstate.edu /instruct/mth251/cq/Stage6/Lesson/quotientRule.html   (465 words)

 Derivative - LearnThis.Info Enclyclopedia   (Site not responding. Last check: 2007-10-13) This definition is used for a partial proof of the Chain Rule. The simplest notation for differentiation that is in current use is due to Lagrange and uses the prime, ′. Messy limit calculations can be avoided, in certain cases, because of differentiation rules which allow one to find derivatives via algebraic manipulation; rather than by direct application of Newton's difference quotient. encyclopedia.learnthis.info /d/de/derivative.html   (1805 words)

 Intermediate Algebra Tutorial on Simplifying Radical Expressions We can use the product rule of radicals in reverse to help us simplify the nth root of a number that we cannot take the nth root of as is, but has a factor that we can take the nth root of. Note that both radicals have an index number of 2, so we are able to put their quotient together under one radical keeping the 2 as its index number. Note that both radicals have an index number of 4, so we are able to put their quotient together under one radical keeping the 4 as its index number. www.wtamu.edu /academic/anns/mps/math/mathlab/int_algebra/int_alg_tut39_simrad.htm   (1113 words)

 Rules of Exponents and Scientific Notation-Chapter 5 Section 1   (Site not responding. Last check: 2007-10-13) Use the quotient rule for exponents, and define a number raised to the zero power. Since multiplication is a fast way of adding and division is a fast way of subtracting things into differents parts, there is a similar rule for raising a quotient to a power. (To raise a quotient to apower, raise the numerator to the power and divide by the denominator to the power). www.rose.edu /faculty/gjackson/elealg/each5-1.htm   (783 words)

 [No title] Derivatives of Quotients Since a special rule was needed for derivatives of products, it seems logical that a special rule is needed for derivatives of quotients also. The derivative of a quotient is a quotient.

 Derivative Shortcuts While these rules are being applied to power functions and polynomials first, they work for any functions. Notice that the derivative of a quotient of functions is not just the quotient of their derivatives; the derivative is somewhat more complex. The derivatives of various other functions can be obtained by the chain rule and the composition of inverse functions. www.empirenet.com /tajames/calculus/notes-derivative-shortcuts.html   (1166 words)

 [No title] We saw a couple of shortcut formulas for derivatives of complicated exponentials and logarithms which are derived from the chain rule. Remember when differentiating implicitly that y is a function of x, and as such must be hit with the chain rule.

 Math Help - Calculus - Properties of Derivatives - Technical Tutoring The quotient rule gives the derivative of one function divided by another. The chain rule is used in the case of a function of a function, also known as a composite function or as a composition of functions. Compostions are particularly useful in the case where a given problem has so-called chained dependencies where the quantity we wish to study is a function of a second quantity which in turn depends on a third quantity. www.hyper-ad.com /tutoring/math/calculus/Properties_of_Derivatives.html   (569 words)

 Product Rule, Quotient Rule, and Chain Rule Tutorial By now you might be thinking that the problem could have been solved with or without the chain rule. After all, once we have determined a derivative, it is much more convenient to "plug in" values of x into a compact formula as opposed to using some multi-term monstrosity. The chain rule is a powerful tool of calculus and it is important that you understand it thoroughly. www.1728.com /chainrul.htm   (367 words)

 [No title] 13.1 ("vector functions") 8: find t-derivative of this vector-valued fn of t: ((t+1)/(t-1), t exp(2t), sec(t)) ANS We differentiate the 3 components individually the first by the quotient rule followed by simplification, the second by product rule, the third by formula (or quotient rule). Result: 2 (-2/(t-1), exp(2 t) + 2 t exp(2 t), sec(t) tan(t)) That first component again in slow-mo: To differentiate (x+1)/(x-1) with respect to x, use quotient rule 2 [T(x)/B(x)]' = [T'(x) B(x) - T(x) B'(x)]/B(x) getting with T(x)=(x+1) and B(x)=(x-1), T'(x)=1, B'(x)=1, so result is 2 2 [(x+1)/(x-1)]' = [x-1 - (x+1)]/(x-1) = -2/(x-1). by quotient rule (or more simply power = -1 rule with chain rule, note get two - signs which yield a + sign inside here...). www.math.temple.edu /~wds/math127hw3s   (1169 words)
