Step 1.1

Reorder $\cos (x)$ and $\sec (x)$ .

$\sec (x) \cos (x) \tan (x)$

Step 1.2

Rewrite $\cos (x) \sec (x)$ in terms of sines and cosines.

$\frac{1}{\cos (x)} \cos (x) \tan (x)$

Step 1.3

Cancel the common factors.

$1 \tan (x)$

Step 2

Multiply $\tan (x)$ by $1$ .

$\tan (x)$

Step 3

Rewrite $\tan (x)$ in terms of sines and cosines.

$\frac{\sin (x)}{\cos (x)}$

Step 4

Convert from $\frac{\sin (x)}{\cos (x)}$ to $\tan (x)$ .

$\tan (x)$
