# Elliptic Functions

Elliptic functions refer to some doubly periodic functions on the complex plane, and historically, they were discovered as the inverses of elliptic integrals. The Jacobi elliptic functions are the standard forms of these functions and can be defined using theta functions. Wolfram|Alpha can compute properties for elliptic functions as well as related elliptic integrals and theta functions.
