Plural of radian. The angle subtended at the centre of a circle by an arc of the circle of the same length as the circles radius
A system for measuring angles wherein a full circle is 2 PI = 6 28 radians The system of measuring angles in radians is common in mathematics and science, though use of degrees is more common outside these fields Angles measured in radians are used to specify rotation angles A value in radians can be converted to degrees by this formula: degrees = radians * 180 0 / 3 142 [see degrees and rotation angle]
A measure of angles A full revolution corresponds to 2* (=6 28 ), half a revolution to , quarter revolution = /2 Correspondingly, 1 rad = 1/(2*) th of a full revolution Conversion to degrees : 1 rad = 180/ deg = 57 29578 deg
Convention for describing the size of an angle with respect to =3 141592 , rather than with respect to "degrees" Conversion between degrees and radians uses the equivalence
