    Solve Ehrenfest's Theorem: Find Position Expectation Value

    Thankyou, I have searched many times on google and other search engines, and have found (as on the websites you have shown me) that m*(d^2/dt^2)<x> = <F> which is a result of the form that I am looking for. But instead of <x> I have <exp(I*theta)>, so a function of theta, as I am...

    Solve Ehrenfest's Theorem: Find Position Expectation Value

    I have been asked to "find a solution to Ehrenfest's Theorem" (in this case for the expectation value of position, of a particle confined to a circle). What does this mean - what kind of answer should i find?
