One radian is the measure of a central angle in a circle which forms an arc on the circle's circumference that is equal to the circle's radius. On a unit circle, one radian is the measure of the angle which forms an arc length of one unit on the circle's circumference. ...
Solving for Coterminal Angles If the angle is greater than 2 pi, subtract 2 pi from the given angle. If the angle is less than 0, add 2 pi to the given angle. You may need to add or subtract 2 pi more than once!!! Trick: Add or subtract the coefficients of pi rather than the ...
