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.
