1. Radian

   The radian, denoted by the symbol rad, is the unit of angle in the International System of Units (SI) and is the standard unit of angular measure used in many areas of mathematics. The unit was formerly an SI supplementary unit (before that category was abolished in 1995). The radian is defined in the SI as being a dimensionless unit, with 1 rad = 1. Its symbol is accordingly often omitted, especially in mathematical writing.

1. radian

   A radian is a unit of angular measure used in many areas of mathematics. It is defined as the angle subtended at the center of a circle by an arc whose length is equal to the radius of the circle. One full circle contains 2π radians, which is approximately 6.28319 radians. It is a standard unit in the International System of Units (SI).

1. Radian

   The radian is the standard unit of angular measure, used in many areas of mathematics. An angle's measurement in radians is numerically equal to the length of a corresponding arc of a unit circle, so one radian is just under 57.3 degrees. The unit was formerly an SI supplementary unit, but this category was abolished in 1995 and the radian is now considered an SI derived unit. The SI unit of solid angle measurement is the steradian. The radian is represented by the symbol "rad" or, more rarely, by the superscript c. For example, an angle of 1.2 radians would be written as "1.2 rad" or "1.2c".
