$\frac{\cos (x) - \sec (x)}{\sin (x)}$

Step 1

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

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

Step 2

Convert from $\frac{1}{\cos (x)}$ to $\sec (x)$ .

$\frac{\cos (x) - \sec (x)}{\sin (x)}$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
