Exploring Fourier Series
by Steven J. Wilson

You can use this page to investigate the behavior of functions defined in the manner of Fourier series. These are given by the formula

All functions derived in this manner will be periodic. Some very interesting graphs are possible with simple formulas for an and bn.
