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

Click For Summary
SUMMARY

The discussion focuses on finding the second derivative of the implicit function defined by the equation x³ + y³ = 1 using implicit differentiation. The first derivative was correctly identified as -x²/y². Participants confirmed that the next step involves differentiating this first derivative to obtain the second derivative. The conversation highlights common challenges faced during the differentiation process.

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! :smile:

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

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