Implicit Differentiation

  • #1

Homework Statement



Use implicit differentiation to find dy/dx if y - sin(xy) = x^2.

What I've got is dy/dx y - cos(xy)(y+x dy/dx) = 2x

I don't know what I did and I don't know where to go from here.

slight mistake: [tex]\frac{d}{dx}(y)\ne\frac{dy}{dx}y[/tex]

after differentiating, group like terms and factor out the y'
