Implicit Diff: Find 2nd Deriv of x^3 + y^3 = 1

[Jacob959]

Homework Statement

Find the second derivative of x^3+y^3=1 by implicit differentiation.

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!

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

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