CalculusCompared with: Unlike derivatives, finite differences measure change over nonzero steps.
Arithmetic progressionRelated: The first differences of an arithmetic progression are all equal.
Secant lineRelated: A finite-difference quotient is the numerical counterpart of a secant slope.
Falling factorialRelated: Finite differences lower the order of falling factorials in a simple way.
Summation by partsNarrower topic: The identity replaces one factor with its finite differences.
