comment Prove that this expression involving $_2 F_1$ and Gamma functions is identically zero
Given the content of the other question you linked to, I'm not quite sure what you're looking for in an answer. Normally I'd suggest finding an integral representation of the hypergeometric and then solve the integral. But it seems you already know the integral representation from the other question.

comment Solve $\int \frac{(\sin x)^2}{a+b\cos x}dx$
@Rafael The standard technique for solving integrals with square-roots of quadratics is the method of Euler substitutions. The method shows that these integrals are nothing to be afraid of. In fact, you should run toward them! :)

comment How to solve $\int \frac{1}{1-y^2}$ with respect to $y$?
The OPprobably has never heard of partial fractions.

comment Why is $s$ used for arc length?
In physics we often parametrize curves by arc length, and say that two points on the curve are separated by $s$.

@YoTengoUnLCD Yes, you are right. The formula has now been corrected. :)

Regarding your problem, could you provide a page number for the parts of in Byrd & Morris you were trying to use?

comment Elliptical Integral that diverges at one point
Welcome to MathSE! I took the liberty of fixing a typo in the first equation since it seemed obvious. While I was at it, I also changed a couple of the tags to something more specific to your problem (there are thousands of posts under the 'calculus' tag, and questions can get lost fast). You are of course free to change them back if you want. :)

revised Elliptical Integral that diverges at one point
Corrected minor typo (missing minus sign in first equation). Replaced 'calculus' and 'limits' tags with 'elliptic integrals' and 'special functions' to better reflect the question topic.
