I am doing a problem involving Jacobian elliptic functions, and am trying to use Mathematica to help. However, I find that I am unable to persuade Mathematica to simplify the expression JacobiDN[p, k^2]^2 + k^2 JacobiSN[p, k^2]^2 which is equal to 1. It is also unable to integrate powers of Jacobian elliptic functions higher than 2, which are given by Byrd and Friedman in terms of elliptic functions and integrals. Can anyone help with this? Thanks, John
