This sounds like a homework assignment, and you should really do it yourself. A tip: in Mathematica's documentation center look up the following: FourierSeries (if you have Mathematica 7) or guide/ FourierAnalysis. For c: look up the documentation of Manipulate[ ]. If you've tried that and it still doesn't work you may come back here.
