comment How to find the number of intersection for $ \rho =\frac{\theta} {2\pi+1} $ and $\rho =\frac {1} {2-\cos\theta} $
$\theta $ can be negative four intersections.

I have little doubt: this formula $\cos{\theta}=2-\dfrac{2\pi+1}{\theta}$ is not equivalent subject conditions , after all, polar coordinates and Cartesian coordinate system is different than one to one.
