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