[edit] Generation function

I removed this:


(due to M. Hirschhorn)

from the subsection on the generating function. It seems to me getting this is too straightforward to really need a cite, and anyway it was unsourced.

[edit] Orthogonality

As far as I can see, the value of the integral should be π / 8 whenever m = n > 0, only when m = n = 0 is the value π / 4 as claimed in the text. This can be shown using the relation

1 - 2S_n(s) = T_n(1 - 2s)\,

with the Chebyshev polynomials Tn and the orthogonality of the Chebyshev polynomials.
