Fourier series no.2 :)

Homework Statement



Hey guys.
So I have this function f(x) between -pi and pi.
I found the Fourier series for it.
Now I need to find the Fourier series for g(x). The problem is, I'm not sure about g(x), is it correct what I did?
Thanks in advance.

Thread 'Finding the nth roots of a complex number'

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
