    1. The problem statement, all variables and given/known data

    . Show that if upload_2015-12-16_16-58-2.png and upload_2015-12-16_16-58-2.png , then upload_2015-12-16_16-58-2.png is constant in time.


    2. Relevant equations


    3. The attempt at a solution

    d<A>/dt=i/h x ([H,A]) + dA/dt
    Therefore if upload_2015-12-16_17-12-9-png.93406.png and dA/dt=0 , then dA/dt=0. Is this it.? :-(
