Please I need help with wavefunctions!!!!

Okay so I have attempted to understand wavefunctions in my pchem class but I am a little lost... Here is the problem.
unnormalized wavefunction (ψ) = e^(iψ) with 0≤ψ≤2∏, normalize this equation

2. Relevant equations

N^2∫ (ψ)^2 dψ

**I uploaded a pic of relevant equations bc it would be too messy to write out on here

3. The attempt at a solution

Okay so I know the answer is N = sqrt (1/2pi)

but I get to this step....

N^2 ∫ e^(-iψ)* e(iψ) dψ

and I am not sure where to go from here... I know ψ^2 = 1 but I am still stuck
1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution

Not sure why you are stuck. The integral of 1 from 0 to 2pi is 2pi. So N^2*(2pi)=1. What's N?
