You have to evaluate in terms of $\sin$ $\cos$ or $\tan$

#### Explanation:

By definition

$\cot \left(\theta\right) = \frac{1}{\tan} \left(\theta\right)$

In terms of $\sin$ and $\cos$

$\tan \left(\theta\right) = \sin \frac{\theta}{\cos} \left(\theta\right)$

$\cot \left(\theta\right) = \frac{1}{\sin \frac{\theta}{\cos} \left(\theta\right)} = \cos \frac{\theta}{\sin} \left(\theta\right)$
