[CHM 331] 9.33

[Andrew J. Pounds]

It's fine with me if you want to do it that way because I essentially 
wrote that equations for you on the board.  Another way to do it would 
be to find the expectation value of the energy using the wavefunction.  
That would require a double integal of the form <Y|H|Y> using the 
notation I showed you in class the other day.  In this latter case you 
would have to use the Hamiltonian with the Laplacian in spherical polar 
coordinates.
