The radian is a unit of angular measure defined such that an angle of one radian subtended from the center of a unit circle produces an arc with arc length 1. A full angle is therefore radians, so there are per radians, equal to or 57./radian. Similarly, a right angle is radians and a straight angle is radians. for measured in radians. Unless stated otherwise, all angular quantities considered in this work are assumed to be specified in radians.
1 The measure of a complete circle, in degrees, is 360 degrees. 2  The measure of a complete circle, in radians, is 2Ï. 3  A radian is defined as the ratio of the arc length, ââsââ to the length of the radius âârââ. 4  One radian is equal to a little less than 57.3 degrees.
