Complete elliptic integrals K(x), E(x)

 x - modulus square.


 MathMate syntax:            EllK(x), EllE(x) 
 Domain:                     0 <= x <= 1 

 Note:  Sometimes another definition is used where the argument is modulus   (not its square, i.e. t²=x). To obtain the elliptic integral of the   argument t calculate EllE (sqrt (t)), EllK (sqrt (t)).
