Simplify the expression (Picture provided)

Rudiy27

Answer:

$\sec(\theta)$

Step-by-step explanation:

We want to simplify

$\frac{\csc(\theta)}{\cot(\theta)}$

We express in terms of the sine and cosine ratios to obtain;

$\frac{\frac{1}{\sin(\theta)} }{\frac{\cos(\theta)}{\sin(\theta)} }$

This is the same as

$\frac{1}{\sin(\theta)} \div \frac{\cos(\theta)}{\sin(\theta)}$

Multiply by the reciprocal to get;

$\frac{1}{\sin(\theta)} \times \frac{\sin(\theta)}{\cos(\theta)}$

Cancel the common factors;

$\frac{1}{\cos(\theta)}=\sec(\theta)$
