- Homework Statement
- If w=x+y and s=(x^3)+xy+(y^3), find ๐w/๐s
- Relevant Equations
- ๐w/๐s=(๐w/๐x)*(๐x/๐s)+(๐w/๐y)*(๐y/๐s)
๐w/๐x=1
and then I wasn't sure about ๐x/๐s, so I tried implicitly differentiating s:
1=(3x^2)(๐x/๐s)+y(๐x/๐s)+x(๐y/๐s)+(3y^2)(๐y/๐s)
And then I shaved my head in frustration.
