Fourier analysis applets and pages on the Web.
Fourier analysis applets on the Web.
Several people have tried to illustrate the idea of Fourier analysis using Java. I suggest that you take a look at the first applet in the list. It is pretty close to what we were trying to do. Unfortunately, it has only a few functions to experement with. The second applet allows one to see how a Fourier series changes as the number of terms increases.
