(a) Write a program for obtaining partial sums of a Fourier series (5).

(b) Apply the program to Probs. 8–11, graphing the first few partial sums of each of the four series on common axes. Choose the first five or more partial sums until they approximate the given function reasonably well. Compare and comment.

Data from Prob. 8

Is the given function even or odd or neither even nor odd? Find its Fourier series. Show details of your work.

Data from Prob. 9

Is the given function even or odd or neither even nor odd? Find its Fourier series. Show details of your work.
