EllipticE

Incomplete and complete elliptic integrals of the second kind

EllipticCE

Complementary complete elliptic integral of the second kind Calling Sequence EllipticE(z,k) EllipticE(k) EllipticCE(k) Parameters

 z - algebraic expression (the sine of the amplitude) k - algebraic expression (the parameter) Description

 • The incomplete elliptic integral EllipticE is defined by

$\mathrm{EllipticE}\left(z,k\right)={\int }_{0}^{z}\frac{\sqrt{-{k}^{2}{t}^{2}+1}}{\sqrt{-{t}^{2}+1}}\phantom{\rule[-0.0ex]{0.3em}{0.0ex}}ⅆt$

 • The complete elliptic integrals EllipticE and EllipticCE are defined by

$\mathrm{EllipticE}\left(k\right)=\mathrm{EllipticE}\left(1,k\right)$

$\mathrm{EllipticCE}\left(k\right)=\mathrm{EllipticE}\left(1,\sqrt{-{k}^{2}+1}\right)$ Examples
