1. The problem statement, all variables and given/known data Show that phi_n will find the proper phi_4. IE: show that it gives the correct normalization constant. Richard Liboff...chapter 7 2. Relevant equations A_n = (2^n * n! * pi^1/2)^-1/2 3. The attempt at a solution I don't know where to start really. I tried some things with < phi | phi > = 1 but honestly stumped.
