05.10.2021 · What is the forward difference operator? The forward difference operator is denoted by Δ and it is the difference between two consecutive values of a function. Lets say we have a function y=f (x) having values corresponding to different values of x as then the first order divided difference is denoted as Δy0=y1-y0.

Forward Difference Formula for the First Derivative We want to derive a formula that can be used to compute the first derivative of a function at any given point.

The formula is called Newton's (Newton-Gregory) forward interpolation formula. So if we know the forward difference values of f at x 0 until order n then the above formula is very easy to use to find the function values of f at any non-tabulated value of x in the internal [a,b].The higher order forward differences can be obtained by making use of forward difference table.

Three basic types are commonly considered: forward, backward, and central finite differences. A forward difference, denoted [], of a function f is a function defined as [] = (+) ().Depending on the application, the spacing h may be variable or constant. When omitted, h is taken to be 1; that is, [] = [] = (+) ().A backward difference uses the function values at x and x − h, instead of the ...
