Break it down into four integrals. I'm sure you know how to integrate \(\sin\theta\) and \(2\).

For \(\sin^3\theta\), write \(\sin^3\theta=\sin\theta\cos^2\theta\sin\theta\), and then the integral of \(\sin\theta\) is easy. Substitute \(u=\cos\theta\) for the integration of \(\cos^2\theta\sin\theta\).

\(\sin^2\theta=\frac{1\cos(2\theta)}{2}\).

Sorry it should be \(2\sin^2\theta=\cos(2\theta)1\).
