Mathematica : Fourier Series Expansions

Please help me in solving this problem.
Please see attached file for full problem description.

Using Mathematica and computer facilities express the function f(x) in terms of Fourier series expansion and show that the series converges as the number of terms increases:

f(x) = x e-x/4 sin(x/3) -&#960; < x < &#960;


Solution Summary

A Fourier series expansion is investigated with the aid of Mathematica.
