Step 1.1

Reorder $2 \cos (x)$ and $\sin (x)$ .

$\sin (x) (2 \cos (x))$

Step 1.2

Reorder $\sin (x)$ and $2$ .

$2 \cdot \sin (x) \cos (x)$

$2 \cdot \sin (x) \cos (x)$

Step 2

Apply the sine double-angle identity.

$\sin (2 x)$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
