Jacobian elliptic function Jacobian elliptic function[jə′kō·bē·ən ə¦lip·tik ′fəŋk·shən] (mathematics) For m a real number between 0 and 1, and u a real number, let φ be that number such that the 12 Jacobian elliptic functions of u with parameter m are sn (u | m) = sin φ, cn (u | m) = cos φ, dn (u | m) = (1-m sin2φ)1/2, the reciprocals of these three functions, and the quotients of any two of them. |
