Here’s a really quick video which takes a different approach to understanding the Fourier Series than we’re used ... into combinations of simple sine or cosine equations which can be handled ...

A mathematical theorem stating that a periodic function f(x) which is reasonably continuous may be expressed as the sum of a series of sine or cosine terms (called the Fourier series), each of which ...

We’ve seen many graphical and animated explainers for the Fourier series. We suppose it is because it is so much fun to create the little moving pictures, and, as a bonus, it really helps ...
