comment Is the Wikipedia version of the Heisenberg equation of motion correct?
Your edit is very helpful, thanks. Note: it turns out I introduced a sign error in the commutator of the equation I was trying to copy from Wikipedia. It's now fixed, but my typo may have leaked into your answer.

Thank you. I'm having trouble distinguishing your answer from yuggib's edit (which has time priority). Is the $t$ vs. $t'$ distinction important? Also, in your last equation, do you mean the full (convective?) time derivative instead of the partial derivative?

comment Is the Wikipedia version of the Heisenberg equation of motion correct?
1) I agree that $dA_H/dt \ne (dA_S/dt)_H$, but I wrote the partial derivative wrt t, $\partial A_H/\partial t=(dA_S/dt)_H$, not the full derivative. In your example, I think the partial derivative applied to $A_H$ would only act on the explicit time dependence ($t^2$), not on $x_H^2$ or $p_H^2$, hence the equality I proposed. 2) My goal is education, not amusement. I don't know if I'm being too picky.
