音标：[ 'reidjən ]

中文翻译与英英解释

	n. 【数学】弧度。

the unit of plane angle adopted under the Systeme International d''Unites; equal to the angle at the center of a circle subtended by an arc equal in length to the radius (approximately 57.295 degrees)
同义词：rad,

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.
