Second Derivative

  1. Oct 23, 2011 #1
    1. The problem statement, all variables and given/known data
    Find the second derivative of x^3+y^3=1 by implicit differentiation.

    3. The attempt at a solution
    I found the first derivative to be x^2/y^2. Do I then use the first derivative and take the derivative of that? I tried to do this, but got stuck on what to do.

    Welcome to PF, Jacob959! :smile:

    Your first derivative should be -x^2/y^2.

    And yes, you should take the derivative from that.
    Where did you get stuck?
