    Tangent Line on a Parametric Curve

    I know that I need a derivative which I got as -3sinst/3cos3t, but I'm stuck from there.

    How do I use implicit differentiation to find dy/dx in this given equation?

    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.
