Input Form





InverseJacobiCN[z, m] == EllipticK[m] - Sum[((-1)^k m^k z^(1 + 2 j + 2 k) Pochhammer[1/2, j] Pochhammer[1/2, k]^2)/ ((1 + 2 j + 2 k) (k + j)! k!), {k, 0, Infinity}, {j, 0, Infinity}] - Sum[((-1)^k m^(k + j + 1) z^(1 + 2 k) Pochhammer[3/2, k + j]^2)/ (2 (1 + 2 k) k! (k + j + 1)! Pochhammer[3/2, j]), {j, 0, Infinity}, {k, 0, Infinity}]
