## Homework Statement

I have some function f(x,t) and I know that both x and t undergo a coordinate transformation according to x = x' + Vt' and t = t'. I am asked to find [itex]\partial(f)/\partial(t')[/itex]

## Homework Equations

Chain rule of calculus

## The Attempt at a Solution

Is

[tex]\frac{\partial{f}}{\partial{t'}}=

\frac{\partial {f}}{\partial{x}}\frac{\partial{x}}{\partial{t'}}

+

\frac{\partial{f}}{\partial{t}}\frac{\partial{t}}{\partial{t'}}\qquad(1)[/tex]

?

I feel like it is, but I also feel like the equation given by (1) is the total derivative wrt t'. That is, I think (1) is the same as

*df/dt'*.

Can someone help clarify this?
