i am wondering if anyone can give me some examples of functions that would help show the relationship between smooth functions and convergence of the fourier series so that i can graph these functions using maple over the period [-Pi,Pi]

I was wondering if anyone can help me with part of this problem iv been stuck on for a while now. I am wanting to write a procedure which will create an array containing a loop of all the Fourier approximations of a function f on     [-Pi, Pi].

Thanks Caitlin
