Fourier Series Example - Step Function

We have a step function f(t) defined as

0 for t = -4 to 0 and

5 for t = 0 to 4.

We demonstrate the infinite Fourier series which produces this step function. In this case, it contains odd sine terms only.

LiveMath presents the expansion of the series in a 'different' order. DO NOT PANIC! It just has its own set of rules for expressing algebra.
