## How do you find the reference angle?

**How to find the reference angle for degrees?**

- 0° to 90°: reference angle = angle ,
- 90° to 180°: reference angle = 180° – angle ,
- 180° to 270°: reference angle = angle – 180° ,
- 270° to 360°: reference angle = 360° – angle .

## What is reference angle?

What is a reference angle. Reference Angle: **the acute angle between the terminal arm/terminal side and the x-axis**. The reference angle is always positive. In other words, the reference angle is an angle being sandwiched by the terminal side and the x-axis. It must be less than 90 degree, and always positive.

## How do you find the exact value of cos 5pi 4?

The value of cos 5pi/4 can be calculated by **constructing an angle of 5π/4 radians with the x-axis, and then finding the coordinates of the corresponding point (-0.7071, -0.7071) on the unit circle**. The value of cos 5pi/4 is equal to the x-coordinate (-0.7071). ∴ cos 5pi/4 = -0.7071.

## Is tan 180 undefined?
