Step 1.1

Factor $6 \sin (x) \cos (x)$ out of $6 \sin (x) \cos^{3} (x)$ .

$6 \sin (x) \cos (x) (\cos^{2} (x)) + 6 \sin^{3} (x) \cos (x)$

Step 1.2

Factor $6 \sin (x) \cos (x)$ out of $6 \sin^{3} (x) \cos (x)$ .

$6 \sin (x) \cos (x) (\cos^{2} (x)) + 6 \sin (x) \cos (x) (\sin^{2} (x))$

Step 1.3

Factor $6 \sin (x) \cos (x)$ out of $6 \sin (x) \cos (x) (\cos^{2} (x)) + 6 \sin (x) \cos (x) (\sin^{2} (x))$ .

$6 \sin (x) \cos (x) (\cos^{2} (x) + \sin^{2} (x))$

Step 2

Rearrange terms.

$6 \sin (x) \cos (x) (\sin^{2} (x) + \cos^{2} (x))$

Step 3

Apply pythagorean identity.

$6 \sin (x) \cos (x) \cdot 1$

Step 4

Multiply $6$ by $1$ .

$6 \sin (x) \cos (x)$
