What justifies being able to ignore Cn for n=0 simply because it diverges?
If you try to calculate c_0 explicitly, you indeed get zero. I believe I miswrote the Fourier series expansion when I summed from -infinity to infinity; since c_0 is zero, the expansion is actually from -infinity to -1 and from 1 to infinity.
Sorry for the lazy arguments, this is an older video.
