A general form of Parseval's Theorem says that if two functions are expanded in a Fourier Series.
Consider a square wave. Write down a Fourier series for this function, plot the original function and the series approximation for n = 1, 2, 3, 4, 5, 10, 20,50.
Plot the original function for -3L < x < 3L, and then also plot the Fourier series for values of n up to n = 1, 2, 3, 4, 5, 10, 20, 50.
