A curve in the xy-plane is defined by xy^2 - x^3y = 6. a) find dy/dx. b) find an equation for the tangent line at each point on the curve with x-coordinate 1. c) find the x-coordinate of each point on the curve where the tangent line is vertical.

a) xy^2 - x^3y = 6 => y^2 + 2xy dy/dx - 3x^2y - x^3 dy/dx = 0 => dy/dx = (3x^2y - y^2) / (2xy...
