elliptic integral of 1st kind: int[1/sqrt(a-cosx)]dx, a>1

[dts5044]

[integral from 0 to pi/2] dx/SQRT(a - cosx)
(a >1)

I need to write this in terms of the elliptic integrals F

the elliptic integral of the first kind is F(k,q) = [integral from 0 to q] du/SQRT(1 - (ksinu)^2)

PLEASE if you know anything about elliptic integrals I need your help!

I do not see a starting point on this!

I know elliptic integrals are tricky and ambiguous and all that...I merely need to REWRITE the given integral in terms of F

thank you in advance for your help!

Re: please help! elliptic integral

no...it is a different problem. It is the same concept, which I have had poor luck getting a response with so far, but it IS a different problem and I hoped maybe someone could see a solution more clearly.
