Geometric series modulo prime a permutation?

Say I have a variable, 1 \le n \le p-1 , where p is prime. Given an integer A , when does A n form a permutation modulo p ? I think it always works (providing A isn't congruent to p), but I'm struggling to prove it. E.g. p=5 , A=2 . 2n gives {2 4 6 8}, which mod 5 is {2 4 1 3}. 3n gives {3 6 9 12}, ...

I find myself struggling with a simple piece of algebra. a exp(i x) - exp(i y) + b = 0 a and b are complex numbers, x and y are real unknowns. So, two unknowns and both the real and imaginary parts of this have to be zero - simple, right? But solving for, e.g. y in terms of x gives y...
