# Incomplete elliptic integral of second kind E(`phi`,k)

`E(phi,k) = \int_0^phi \ sqrt(1-k^2*sin^2 theta) d theta` `-1<=k<=1`

This tool is a calculator of incomplete elliptic integral of second kind.

`E(phi,k) = \int_0^phi \ sqrt(1-k^2*sin^2 theta) d theta`

`phi` : amplitude

k : module or eccentricity ( -1 <= k <= 1)

By substituting `x = sin(phi)` and `t = sin(theta)`, we obtain another form of the same function :

Incomplete elliptic integral of second kind (x)
