    Help Isolating a Variable

    It's been awhile since I was in math, and I'm in a Calculus class right now. I need to find dx/dy of an implied function, and I'm having trouble re-arranging the function to do so. The equation I have is:

    sin (X^2+y^2) = xy + 1

    how do I isolate for y?

    You can't. You're expected to get dy/dx using implicit differentiation.
