I need to find the area enclosed by two polar graphs $r=\sin\theta$ and $r=\cos2\theta$ within the positive quadrant. However I am unsure which section of the curves i am to use to find the enclosed area as several areas could be taken as the correct on in my opinion. Which area should I find? Also is this a common issue to have with polar graphs that I'm just not used to?
I also have found that the graph cross at the origin and $(0.5,\frac{1\pi}{6})$
