. This is now a Quadratic in , so solve using the Quadratic Formula.
the solution of dy/sx dont seems to be integrate able at all. i dont think this is gonna work! btw these question are from section where we have to use substitutions like x = r.cost & y = r.sint
Just use the Quadratic formula. It's an equation of the form . Here . So the solutions are . It's ok to keep your solution in terms of and . You don't need to do any integration at all.
