## Homework Statement:

- If w=x+y and s=(x^3)+xy+(y^3), find πw/πs

## Relevant Equations:

- πw/πs=(πw/πx)*(πx/πs)+(πw/πy)*(πy/πs)

πw/πx=1

and then I wasn't sure about πx/πs, so I tried implicitly differentiating s:

1=(3x^2)(πx/πs)+y(πx/πs)+x(πy/πs)+(3y^2)(πy/πs)

And then I shaved my head in frustration.
