InverseJacobiDN[v, m]
gives the inverse Jacobi elliptic function dn^(-1)(v❘m).
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • dn^(-1)(v❘m) gives the value of u for which v=dn(u❘m).
  • InverseJacobiDN has branch cut discontinuities in the complex z plane with branch points at and infinity, and in the complex m plane with branch points 1-z^2 and infinity.
  • The inverse Jacobi elliptic functions are related to elliptic integrals.
  • For certain special arguments, InverseJacobiDN automatically evaluates to exact values.
