# Complete Elliptic Integral Of The First Kind?

Calculus Level 5

$\dfrac{1}{2}\int_{-\pi/2}^{\pi/2}\dfrac{d\theta}{\sqrt{1-(\sqrt{2}-1)^2\sin^2{\theta}}}=\dfrac{\sqrt{\sqrt{A}+B}}{A^{C/D}\sqrt{\pi}}\Gamma\left(\dfrac{B}{E}\right)\Gamma\left(\dfrac{F}{E}\right)$

The equation above holds true positive integers $$A,B,C,D,E$$ and $$F$$ such that $$A$$ is square-free and $$C,D$$ are coprime. Find $$A+B+C+D+E+F$$.

Notation: $$\Gamma(\cdot)$$ denotes the Gamma function.
