Numerical differentiation: Step size, Finite differences & Complex-variable methods

In numerical analysis, numerical differentiation algorithms estimate the derivative of a mathematical function or subroutine using values of the function. Unlike analytical differentiation, which provides exact expressions for derivatives, numerical differentiation relies on the function's values at a set of discrete points to estimate the derivative's…
