## Homework Statement

For what values does the limit exist?

[tex]Lim_{n\rightarrow}\infty[/tex]([tex]\frac{z}{z conjugate}[/tex])^n

## Homework Equations

## The Attempt at a Solution

[(x+iy)/(x-iy)]^n

I just don't know how to tell when it exists. For even values of n because then there would be no sign changes?
