Definition:Elliptic Integral of the Second Kind/Complete

Special Function
The integral:
 * $\displaystyle \int \limits_0^{\pi / 2} \sqrt{1 - k^2 \sin^2 \phi} \, \mathrm d \phi$

is known as the complete elliptic integral of the second kind, and is a function of $k$, defined on the interval $0 < k < 1$.

It is denoted $E \left({k}\right)$.
