Love a gif version I saw of this recently, so fascinating.
I think this would be neater if it had a small text field, where you could put in a JS function, and it would do an approximate fourier series based off of a segment of the function.
Kind of feel like someone should make a page that fully explains all the levels of this graphic:
- the circles let you graph f(x)=a*sin(nx+phase) (cosine on the horizontal projection)
- attaching the circles is the same as adding, so you actually have a way of drawing out the first parts of a fourier series
- any periodic function can be represented through all these spinning circles
