WebAug 13, 2024 · This is a quadratic equation for r whose solutions are. r = 4 cos θ ± 16 cos 2 θ − 16 ( cos 2 θ − 1) 2 cos 2 θ − 2 = 4 ( cos θ ± 1) 2 ( cos 2 θ − 1). Since r is non-negative and the denominator is non-positive, we must take the solution. r = 4 ( cos θ − 1) 2 ( cos θ − 1) ( cos θ + 1) = 2 cos θ + 1. Share.
