Simplify with factoring out.

Tap for more steps...

Step 1.1

Factor $\cos (x)$ out of $\cos (x) \csc^{2} (x)$ .

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

Step 1.2

Factor $\cos (x)$ out of $- \cos (x) \cot^{2} (x)$ .

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

Step 1.3

Factor $\cos (x)$ out of $\cos (x) (\csc^{2} (x)) + \cos (x) (- 1 \cot^{2} (x))$ .

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

Step 2

Apply pythagorean identity.

$\cos (x) \cdot 1$

Step 3

Multiply $\cos (x)$ by $1$ .

$\cos (x)$
