describes the process of expressing a real number as the radian measure of an angle. It explains why angles are expressed in degrees, minutes, and seconds. Three examples show how to express an angle in degree-minute-second notation, in radians, and how to find the length of an arc on a circle. Three exercises with solutions are provided.
