This script allow you to calculate and visualize the Fourier's series of generic f(x)function. The script it's very simple. Set the domain extension choosing the "a" value; after that set the series's order 'n' and than chose your f(x) "f_x". The series will be calculated and represented in 3 ways: S_standard , S_armonic, S_complex.
