1. The problem statement, all variables and given/known data dy/dx = [3(x^2)y - y^2] / [2xy - x^3] Find the x-coordinate of each point on the curve where the tangent line is vertical. 2. Relevant equations original equation is x(y^2) - (x^3)y = 6 3. The attempt at a solution i set the denominator of the deriv. to 0, but i have no idea where to go from there. am i solving for x or y? is there a way i can eliminate one of the variables? do i need to plug anything into the orig. equation?
