Total time derivatives of operators in elementary quantum mechanics
... which implies that the total derivative obeys the same algebraic rules as ordinary derivatives. Because this total time derivative is not defined to be a rate of change of anything, some may prefer to use a different symbol for it, for example, D t instead of d/dt, but the latter notation will be us ...
