tan (x) \cdot cot (x)

$\tan (x) \cdot \cot (x)$

Step 1

Reorder

tan (x)

$\tan (x)$ and

cot (x)

$\cot (x)$ .

cot (x) \cdot tan (x)

$\cot (x) \cdot \tan (x)$

Step 2

Rewrite

tan (x) \cdot cot (x)

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

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

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

Step 3

Cancel the common factors.
