WebSo we are looking at $$3+\frac{5}{2}\left(\frac{3}{5}\sin 2\theta +\frac{4}{5}\cos 2\theta\right).$$ This is $$3+\frac{5}{2}\sin(2\theta+\alpha),$$ where $\alpha$ is the angle whose cosine is $3/5$ and whose sine is $4/5$. Note by the way that our expression is always positive, since $\sin(2\theta+\alpha)$ can never be less than $-1$.
