New issue 1792 by kirzhanov: SymPy does not integrate a real power of
sine/cosine
http://code.google.com/p/sympy/issues/detail?id=1792
I want to get a general explicit expression of an integral of this function:
delta
cos

The wolfram alpha result (for reference): -(cos^(1+r)(x) csc(x) 2F1(1/2,
(1+r)/2, (3+r)/2, cos^2(x)) sqrt(sin^2(x)))/(1+r).

I think we would first need to implement the hypergeometric function,

I'm sorry for my error, that (in latex) really was antiderivative to
1+delta
cos (theta)
and not to
delta
cos (thet

This seems unlikely to me. As far as I can tell, cos(x)^r is not a meijer
g-function unless r is a positive integer.
The way to do

That's a shame, because WolframAlpha can do it
