I am taking a power series and matrices class and as part of the review we are being asked to determine the possible polar angles if we have the cube roots of 1 + i

I am at a complete loss as to how to tackle this. Would I just use r = the square root of (1^1/3 + 1^1/3) since the coefficient for i is one

and then use polar form: z = r cos angle + i r sin angle?????

Thanks to all of you who take time to help out struggling math students!!! Frostking
