1. The problem statement, all variables and given/known data

Calculate the derivative of f(x,y,z)=($$\frac{z^3}{y}$$ , $$\frac{x^3}{z}$$) at (1,2,3)

2. Relevant equations

3. The attempt at a solution

Okay guys and gals, this problem was on my final today. It was the only problem I had a gutsy but unsure feeling about. The actual answer itself does not matter to me, rather the concept of understanding is.

I basically interpreted the problem this way:

Find the partial derivatives with respect to x,y,z for the two functions of f. So it is a 2 x 3 matrices. Plug in the points and you are done.

Did anyone else get this interpretation of the problem/solution?
