Do you cube and add 2pi to the arguments? For the second part is it acceptable to rewrite 2 in exponential form and then continue from there? Thanks

Thanks for the reply. So for e^(ipi/4) you would get e^(11pi/12), e^(19pi/12) and so on?

Hint on the other one. Why doesn't the idea of rotations work with ${2}$?
