Homework Help: Quick Partial Derivatives question - exp(x+z)

  1. Jul 15, 2009 #1
    1. The problem statement, all variables and given/known data
    Finding the partial derivative with respect to y, so del(f)/del(y)

    2. Relevant equations
    exp(x+z) - that is e^(x+z)

    3. The attempt at a solution
    I firstly thought this was just e^(x+z) but then i realised, shouldn't it be just 0? Since you're finding the partial derivative with respect to y, and since there's no y variable in there, wouldn't it be 0, ie treating the whole equation as a constant?
