Commutator of and

We can use the commutator to help us. Remember that .

It is usually not wise to use the differential operators and a wave function crutch to compute commutators like this one.
**Use the known basic commutators when you can.**Nevertheless, we can compute it that way.

It works pretty well for this particular case, but not if I have to some power...
