0 <=theta<=pi/3 and 5/3 pi<=theta<=2 pi

Explanation:

r=3 cos theta and r=2-cos theta.

3 cos theta =2-cos theta
4 cos theta = 2
cos theta = 1/2

theta = pi/3 = 60^0 and 5/3pi = 300^0 for 0 <= theta <= 2 pi

If we plot a graph, we can find that the region cover the inside r=3 cos theta and r= 2-cos theta are 0 <=theta<=pi/3 and 5/3 pi<=theta<=2 pi for 0<=theta<=2 pi
