A robotic welding tool follows a path in the xyxyxy-plane described by the implicit equation
3y2−12y=4x2+16x−16 3y^2 - 12y = 4x^2 + 16x - 16 3y2−12y=4x2+16x−16Determine an expression for dydx\frac{dy}{dx}dxdy in terms of xxx and yyy.
The path of the tool is discontinuous, and it cannot operate within an exclusion zone defined by the xxx-interval (p,q)(p, q)(p,q).
By considering the points on the curve where the tangent is vertical, find the exact values of ppp and qqq.
