1. The problem statement, all variables and given/known data I am a little confused on the steps to take to solve these kinds of functions. Solve: cosh z = 2i 3. The attempt at a solution We were given identities for sinh z = 0 and cosh z = 0 and also other identities like cosh(z) = cos (iz) So cos (iz) = 2i cos (z) would be 2i for (Pi/2 + 2kPi) right? So cos(iz) = i(Pi/2 + 2kPi) = 2i? However, this doesn't look right.
