**Fourier Series**

This is a demonstration of a Fourier series. The index can be
changed with a slider.

### Technical Information

C.a.R. is no programming language. Currently, it does not
even have a finite sum. So the construction is done with 10 functions, each
adding sin(kx)/k to the previous one, and validity by using an if()
construction.
