Really not sure how to start this one, i tried breaking it into it's real and imaginary components but didn't get far with that.

Is it something to do with taking the log?

If so i'm a little lost on how to do it

Surely you've been taught about the complex log function ....?

You should know that where is the principle argument of z and n is an integer. (The z here is not to be confused with the z in your question, by the way). Go back and review your class notes and textbook. - Jun 1st 2011, 08:22 PMProve It

when i try that i get a messy answer.

did i do something wrong? - Jun 1st 2011, 09:03 PMProve It
Yes, the imaginary part of is , not .
