comment Why is my output equal to my input?
@funnypony If you look closely at Maple's output you'll see it isn't really a closed form solution.

comment Problem with DensityPlot Plot3d of Heavisde function
No, it is not good. Try it on a clean kernel and you'll get an infinite recursion for obvious reasons. You'll want something like w[x_, y_] = Sum[HeavisidePi[x - i/100], {i, 1, 99}].

Please copy all the actual code you used. Don't retype it, as you have clearly typos in the text (DenistyPlot instead of DensityPlot).

Your definition doesn't make sense. Is this really what you entered in Mathematica?

comment Fourier plot issue
For the spectrum you should not separate the imaginary and real parts of your points in a flattened list. Use SamplePts = Table[c[time[i]] /. r, {i, 0, numpoints}]

With that edit ListPlot just works. What precisely is your problem?

comment Fourier plot issue
You haven't defined r, and you have to DSolve or NDSolve your equation before c becomes anything useful...

comment How to create my own procedures in mathematica?
Learning points in this case are: Print does not return its argument, it prints it; = (Set) differs from := (SetDelayed), and ; (CompoundExpression) has meaning too. I'd suggest looking up them all.
