To some people, numerical differentiation sounds a trivial task, which can be easily done by
difference formulas. However, cancellation is a serious problem with these formulas, especially the
ones for higher order derivatives. In order to solve this problem, the complex calculus is usually
employed. There are two main approaches, and the aim of this article is to give a brief review of
them: These are complex step differentiation formulas, and the Cauchy integral approach
