WebIn radian measure, the reference angle must be < π 2 . Basically, any angle on the x-y plane has a reference angle, which is always between 0 and 90 degrees. The reference angle is always the smallest angle that you can make from the terminal side of an angle (ie where the angle ends) with the x-axis. WebThe formula to find the coterminal angles of an angle θ depending upon whether it is in terms of degrees or radians is: Degrees: θ ± 360 n Radians: θ ± 2πn In the above formula, θ ± 360n, 360n means a multiple of 360, where n is an integer and it denotes the number of rotations around the coordinate plane.
