Intersection points of two polar curves I was asked to find the area inside $r=3cos\theta$ and outside $r=1+cos\theta$ (see figure)

My question is, how do i find the intersection points, I was taught to make $1+cos\theta = 3cos\theta$ and solving it we get $\theta=\pi/3$ and $\theta =5\pi/3$, but as you can see the curves meet at the pole as well, how do I find this point? (I do not need this for the área but I'm just curious)

Observe one of the points of intersection is given by
\begin{align}
(r\cos\theta, r\sin\theta) 
\end{align}
where $r = 3\cos \frac{\pi}{3}$ and $\theta = \frac{\pi}{3}$.
