Finite difference

In mathematics, a finite difference is like a differential quotient, except that it uses finite quantities instead of infinitesimal ones.

Calculus of finite differences

One important aspect of finite differences is that it is analogous to the derivative. This means that difference operators, mapping the function f to a finite difference, can be used to construct a calculus of finite differences, which is similar to the differential calculus constructed from differential operators.
