10.09.2018 · The finite difference, is basically a numerical method for approximating a derivative, so let’s begin with how to take a derivative. The definition of a derivative for a function f (x) is the following Now, instead of going to zero, lets make h an arbitrary value.

Finite difference methods for PDEs are essentially built on the same idea, but approximating spatial derivatives instead of time derivatives.
