# Normalization Factor

I was given this wavefunction and asked to find the normalization factor, N.

lpsi>= N[2 lphi1> - lphi2> +i lphi3>]

I am confused as to how to get this problem going. Do I just take <psi l psi> and set it equal to one? I probably have many more questions to ask, but I'll save those for later.

Yes, you want to set $$\langle \psi | \psi \rangle = 1$$, which will determine N up to a phase. Note that the calculation is quite easy if 1, 2, and 3 are all orthogonal states.
