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

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

Step 1

Convert from

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

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

tan (x)

$\tan (x)$ .

tan (x) + \frac{cos (x)}{sin (x)}

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

Step 2

Convert from

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

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

cot (x)

$\cot (x)$ .

tan (x) + cot (x)

$\tan (x) + \cot (x)$
