Calculate the Derivative

  1. Jun 10, 2010 #1
    1. The problem statement, all variables and given/known data

    Calculate the derivative of f(x,y,z)=([tex]\frac{z^3}{y}[/tex] , [tex]\frac{x^3}{z}[/tex]) 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?
