I'm supposed to derive this monster!
[tex] \frac{1}{2} + \frac{2}{\pi} \sum^{\infty}_{k = 1}\frac{1}{2k-1}sin(2k-1)x = \left\{^{0 \ for \ -\pi < x < 0}_{1 \ for \ 0<x<\pi} [/tex]
I don't even know where to start right now. And no examples to work from. Can anyone get me started?
the Chapter is on Fourier Expansions for solutions to Laplace's Equation.
Any direction at all would be really appreciated.
