1. The problem statement, all variables and given/known data I need help on a little review please. z=2-i What is arg(iz) 2. Relevant equations Well iz= 1+2i 3. The attempt at a solution I think this should end up being arg(2i/1) But this doesn't seem to make sense because I am wanting to find an angle here right? I am somewhat confused. This is supposed to be an inverse tangent type problem, correct?
