This code showcases a simple demonstration of how the Fourier series can approximate a piecewise function. The code is a simple application of the libraries numpy and matplotlib, which are scientific ...

This repo contains some Python tooling to simplify linear combinations of piecewise linear functions, then finally emit them (and their first derivatives) as Excel formulas. The motivating application ...

Of course this produces the same derivative values as the usual limit-based definitions of the derivative. What makes this possibly preferable to the usual formulas, though, is that it arises out of ...
