Expert Solution

The exact trigonometric ratio of the

**Given information: **

**Formula Used: **

Trigonometric ratios are given by the following formula:

**Calculation:**

The given value of radian is

Know that:

In one full rotation the angle is

Now, rewrite the given angle in the standard position:

Thus, the given angle

This angle is drawn as below:

Here, the triangle is fixed at terminal

Therefore, trigonometric ratios are given as:
