Actually you can simplify a little bit by \[A(shaded)=\frac{1}{2}r^2(pi\theta)\frac{1}{2}(r^2)(\sin(pi\theta))\] \[A(shaded)=\frac{1}{2}(r^2)(pi\theta\sin(pi\theta))\]

POB=2AP \[\frac{1}{2}r^2 \theta=2(\frac{1}{2}r^2(pi\theta\sin(pi\theta))\] \[\theta=2(pi\theta\sin(pi\theta))\] \[\theta=2pi2\theta2\sin(pi\theta))\] \[3\theta=2(pi\sin(pi\theta))\]
