	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.

	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."

	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.

		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.

		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.
