- 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.
