$\frac{\sin (θ) - \csc (θ)}{\cos (θ)}$

Step 1

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

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

Step 2

Convert from $\frac{1}{\sin (θ)}$ to $\csc (θ)$ .

$\frac{\sin (θ) - \csc (θ)}{\cos (θ)}$

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