Forward difference method calculator
Webr (r-1) . . . (r - n +1) D nf0. 2! n! The formula is called Newton's (Newton-Gregory) forward interpolation formula. So if we know the forward difference values of f at x0 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 ... WebA 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 values at x + h and x : Finally, the central difference is given by

Central differences needs one neighboring in each direction, therefore they can be computed for interior points only.
