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

Step 1

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

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

Step 2

Rewrite in terms of sines and cosines, then cancel the common factors.

Step 2.1

Add parentheses.

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

Step 2.2

Rewrite $\frac{1}{\cos (x)} \tan (x) \cos (x)$ in terms of sines and cosines.

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

Step 2.3

Cancel the common factors.

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

Step 3

Combine $\frac{1}{\cos (x)}$ and $\sin (x)$ .

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

Step 4

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

$\tan (x)$
