Complementary jacobi amplitude

  1. Apr 4, 2014 #1
    I found this identity in the wiki


    One propertie of the ellipitc integral is: K(k') = K'(k), all this set of ideia seems answer an old doubt, ie, exist a complementary for jacobi amplitude?


    ##\Delta(\phi, k) = \sqrt{1-k^2 \sin(\phi)}##


    ##\Delta(\phi, k') = \Delta ' (\phi, k) = \sqrt{1+k^2 \cos(\phi)}##
