I Jacobi Elliptic Functions

  1. Oct 17, 2017 #1
    When doing a problem on a pendulum undergoing elliptical motion, I came across sn(z), which is apparently a "Jacobi Elliptic Function". When I looked into it further, I saw that these functions are essentially circular trigonometric functions but about an ellipse instead of a perfect circle. Can someone give me a more strict definition of each of the elliptic functions? Thanks.
