Homework Help: Partial derivatives help!

  1. Oct 24, 2012 #1
    1. The problem statement, all variables and given/known data

    Find all first and second partial derivatives of the following function:

    z = e^(-ET) where E and T are functions of z.

    I know how to do partial differentiation, but not when the variables are functions of z? I don't understand - is there some sort of implicit partial differentiation?

    2. Relevant equations

    3. The attempt at a solution
    I have no idea at how to start!
