Find the area of the region common to [itex]r=4\sin\theta[/itex] and [itex]r=4\cos\theta[/itex](adsbygoogle = window.adsbygoogle || []).push({});

How can I find the limits of integration? I know one of the limits is pi/4 by setting r1 = r2 but I can't find the other one because it is different for each equation. The graph shows it intersecting at (0,0), but thats a different theta for each equation.
