elliptic_e( z , m )

The incomplete elliptic integral of the second kind of z and parameter m in SageMath. Defined by

\[ E(z|m) = \int_0^z du \sqrt{ 1 - m \sin^2 u } \]

Note that all elliptic integrals in SageMath use the parameter rather than the elliptic modulus k, which is related to the parameter by \( m = k^2 \).
