$(1 - \cos^{2} (x)) \cot^{2} (x)$

Step 1

Apply pythagorean identity.

$\sin^{2} (x) \cot^{2} (x)$

Step 2

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

$\sin^{2} (x) {(\frac{\cos (x)}{\sin (x)})}^{2}$

Step 3

Apply the product rule to $\frac{\cos (x)}{\sin (x)}$ .

$\sin^{2} (x) \frac{\cos^{2} (x)}{\sin^{2} (x)}$

Step 4

Cancel the common factor of $\sin^{2} (x)$ .
