# Finite difference mathematical notation

Finite difference is a recurring research-paper notation family. Approximates a derivative from function values separated by a finite step rather than…

## Public overview

Finite difference is a recurring research-paper notation family. Approximates a derivative from function values separated by a finite step rather than differentiating the expression analytically.

Finite difference: Approximates a derivative from function values separated by a finite step rather than differentiating the expression analytically. Example: Estimate slope from two nearby function evaluations.
