Hi, I really need help with this as exam is tomorrow
The question is to find the points on the cardioid r=a(1+costheta) where the tangents are perpendicular to the initial line
here is the answer
http://gyazo.com/e8b4cbd36f0ef71d0cdf13be256d8618
Why is pi not included in the solution, while if I was finding parallel to the initial line then pi would be included.
please help
