Solving Derivatives

  1. Sep 3, 2009 #1
    1. The problem statement, all variables and given/known data
    Find the Derivative of
    Code (Text):
    f(x) = [tex]\frac{6}{z^{2}+z-1}[/tex]

    2. Relevant equations



    3. The attempt at a solution
    Code (Text):
    [tex]6\left(z^{2}+z-1\right)^{-1}[/tex]
    Use Chain Rule to conclude
    Code (Text):
    [tex]\frac{-12z - 6}{(z^{2}+z-1)^{2}}[/tex]
    Is this right?

    Yes that is correct.


    btw that f(x) should be f(z)
