Homework Statement
If u=x^3 + 3xy + y^3, determine du/dx on the ellipse 2x^2+3y^2=1
2. The attempt at a solution
Imagine I just use partial derivative somehow, but I'm not sure what the question is asking by on the ellipse. I have a feeling its just something simple that I'm overlooking. Any help is appreciated. Thanks
