left inverse — noun A related function that, given the output of the original function returns the input that produced that output. In order for a function to have a left inverse it must be injective. Ant: right inverse … Wiktionary
Inverse element — In abstract algebra, the idea of an inverse element generalises the concept of a negation, in relation to addition, and a reciprocal, in relation to multiplication. The intuition is of an element that can undo the effect of combination with… … Wikipedia
Inverse function — In mathematics, if fnof; is a function from A to B then an inverse function for fnof; is a function in the opposite direction, from B to A , with the property that a round trip (a composition) from A to B to A (or from B to A to B ) returns each… … Wikipedia
Inverse distance weighting — (IDW) is a method for multivariate interpolation, a process of assigning values to unknown points by using values from usually scattered set of known points. A general form of finding an interpolated value u for a given point x using IDW is an… … Wikipedia

Inverse semigroup — In mathematics, an inverse semigroup S is a semigroup in which every element x in S has a unique inverse y in S in the sense that x = xyx and y = yxy. Inverse semigroups appear in a range of contexts; for example, they can be employed in the… … Wikipedia

Inverse functions and differentiation — In mathematics, the inverse of a function y = f(x) is a function that, in some fashion, undoes the effect of f (see inverse function for a formal and detailed definition). The inverse of f is denoted f^{ 1}. The statements y=f(x) and x=f 1(y) are … Wikipedia
