1. The problem statement, all variables and given/known data ((-1+i)/(√2))^1002 find polar and cartesian form 2. Relevant equations 3. The attempt at a solution So I started by finding |z|=1 and Arg(z)= arctan (-1) = 5pi/6 so 1^(1002)*e^(i*5pi/6)*1002 =1*e^(i*835pi) but thats as far as I got because the answer says -i, but to get that term I need 1*e^-ipi/2 any thoughts??
