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

Step 1

Convert from $\frac{1}{\cos (x)}$ to $\sec (x)$ .

$\sin (x) \cdot \sec (x)$

Step 2

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

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

Step 3

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

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

Step 4

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

$\tan (x)$
