1. The problem statement, all variables and given/known data Find |exp(√i)|. 2. Relevant equations 3. The attempt at a solution I scanned my working as attached, it seems ok to me but I dont understand why it's wrong.. The answer scheme ignores the exp(i sin (pi/4) ) part and writes the answer as exp(cos (pi/4)) = exp(1/√2). Would appreciate any help!
