I've seen this example for using the Heisenberg equation of motion to solve the Simple Hamonic Oscillator.

http://en.wikipedia.org/wiki/Heisenberg_picture#Commutator_relations"

However, if you wereonlyinterested in one variable, lets say position, on how the the position operator varies in time and its resulting expectation values: Would is it neccessary to find and solve the equation of motion for P as well?

Also once one has the relevant equation of potion:

[tex]\frac{dX(t)}{dt} = \frac{p(0)}{m} [/tex]

Why is it so often solved by differentiating the equation a second time and solving, rather than just integrating?
