To get coterminal angles, you simply have to **add or subtract 2π**. In this problem, we are looking for a coterminal angle that is between 0 and 2π, so we will add 2π to −1924π.

## How do you find a Coterminal angle with pi?

To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360° if the angle is measured in degrees or 2π if the angle is measured in radians.

## What is the formula for Coterminal angle?

We can find the coterminal angles of a given angle by using the following formula: Coterminal angles of a given angle θ may be obtained by either adding or subtracting a multiple of 360° or 2π radians. Coterminal of θ = θ + 360° × k if θ is given in degrees. Coterminal of θ = θ + 2π × k if θ is given in radians.

## What is Coterminal angle between zero and 360 degrees to the given angle of degrees?

Coterminal angle of 0°: 360°, 720°, -360°, -720° Coterminal angle of 1°: 361°, 721°, -359°, -719°

## How do I find the reference angle?

So, if our given angle is 110°, then its reference angle is 180° – 110° = 70°. When the terminal side is in the third quadrant (angles from 180° to 270°), our reference angle is our given angle minus 180°. So, if our given angle is 214°, then its reference angle is 214° – 180° = 34°.

## What is the reference angle for 200o?

A 200-degree angle is between 180 and 270 degrees, so the terminal side is in QIII. Do the operation indicated for that quadrant. Subtract 180 degrees from the angle, which is 200 degrees. You find that 200 – 180 = 20, so the reference angle is 20 degrees.

## How do you know if two angles are Coterminal?

Coterminal Angles are angles who share the same initial side and terminal sides. Finding coterminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians.

## What is a positive angle less than 2pi that is Coterminal with?

A positive angle less than 2pi that is coterminal with the angle -11pi over 3 is π/3 radians.

## What angle in degrees is equivalent to 25π 36 radians?

Tan 125 degrees in radians is written as tan (125° × π/180°), i.e., tan (25π/36) or tan (2.181661…).

## How do you change a negative angle to a positive?

Given a negative angle, we add 360 to get its corresponding positive angle. When an angle is -360°, it implies that the object made more than one cycle in clockwise direction.
