I've tried looking online, but I haven't found the answer. For instance, when can you say (dFx/dt)=(dF/dt)x, where subscript x indicates partial differentiation with respect to x.
I know that partial differentiation is pretty much always interchangeable, but what about in this case? I have a physics problem, a Lagrangian, and interchanging how I asked gives the right answer, but I want to make sure it's really legit.
Thanks.
