In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/ x or x â1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a / b is b / a.For the multiplicative inverse of a real number, divide 1 by the number.For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4.he notation f â1 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)â1 is different from the inverse sin of x, denoted sinâ1 x or arcsin x.
In mathematics, an inverse function is a function that reverses another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa. i.e., f(x) = y if and only if g(y) = x.
