According to Carroll, [itex]\nabla \phi[/itex] is covariant under rotations. This really confuses me. For example, how could equations like [itex]\vec{F}=-\nabla V[/itex] be rotationally covariant if force is a contravariant vector?
I know this is strictly speaking more of a mathy question, but I still figured this was the best place to ask this question.
