Determine the reference angle
WebWhen finding reference angles, it can be helpful to keep in mind that the positive x -axis is 0° (and 360° or 0 radians (and 2π radians); the positive y -axis is 90° or \frac {\pi} {2} 2π radians; the negative x -axis is 180° or π radians; and the negative y -axis is 270° or \frac {3\pi} {2} 23π radians. Let's get started with an easy example. WebFind the Reference Angle (16pi)/3 16π 3 16 π 3 Find an angle that is positive, less than 2π 2 π, and coterminal with 16π 3 16 π 3.
