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

Step 1

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

$\frac{\cos (x) - \sin^{2} (x)}{\cos (x)} \cdot \frac{1}{\sin (x)}$

Step 2

Multiply $\frac{\cos (x) - \sin^{2} (x)}{\cos (x)}$ by $\frac{1}{\sin (x)}$ .

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