Relations to inverse functions

The complete elliptic integral is related to Jacobi amplitude by the following formula, which demonstrates that Jacobi amplitude is the some kind of inverse function to the elliptic integral :

Representations through other complete elliptic integrals

All complete elliptic integrals , , and can be represented through other complete elliptic integrals by the following formulas:
