Homework Help: Partial Differentiation with 2 variables

  1. Mar 16, 2010 #1
    1. The problem statement, all variables and given/known data

    When I write 'd' I mean the partial differentiation symbol 'del' here...

    Find dz/dx and dz/dy of:


    I'm guessing this isn't a case of simply pretending the 'f( )' isn't there, how do I approach this problem?

    2. Relevant equations

    3. The attempt at a solution

    when you say
    you want to find the first partial derivative of z in terms of x.
    meaning, that you treat y as a constant and x as a veritable

    similarly goes with dz/dy
