Sun May 18 2003 14:30:00 GMT-0400 (Eastern Daylight Time) · The notation f −1 is sometimes also used for the inverse function of the function f which is not in general equal to the multiplicative inverse . For example the multiplicative inverse 1/(sin x ) = (sin x ) −1 is the cosecant of x and not the inverse sine of x denoted by sin −1 x or arcsin x . Only for linear maps are they strongly related …

In mathematics a function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set. Typical examples are functions from integers to integers or from the real numbers to real numbers.. Functions were originally the idealization of how a varying quantity depends on another quantity. For example the position of a planet is a …

Definitions. A function () is called a rational function if and only if it can be written in the form = ()where and are polynomial functions of and is not the zero function .The domain of is the set of all values of for which the denominator () is not zero.. However if and have a non-constant polynomial greatest common divisor then setting = and = produces a rational function
