## Calculus 8th Edition

The graph of $$r=\frac{3}{2-2\cos\theta}$$ is a side-way parabola with eccentricity $1$.See the attached graph.
As we are given that $r=\frac{3}{2-2cos\theta}$ This can be rewritten as: $r=\dfrac{(3/2)}{1-\cos\theta}$ $r=\dfrac{(1).(3/2)}{1-(1).cos\theta}$ The graph of $$r=\frac{3}{2-2\cos\theta}$$ is a side-way parabola with eccentricity $1$.See the attached graph.
