Question

How to find positive and negative coterminal angles

Answer 1

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

Answer 2

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. Example 1: Find a positive and a negative angle coterminal with a 55°angle. A −305°angle and a 415°angle are coterminal with a 55°angle.
