Definition of radian in English:

radian

noun ˈreɪdɪənˈreɪdiən

Geometry

A unit of measurement of angles equal to about 57.3°, equivalent to the angle subtended at the centre of a circle by an arc equal in length to the radius.
〔几何〕弧度
Example sentencesExamples
- The sliding displacement between doublets may be found by multiplying the shear angle, in radians, by the interdoublet distance.
- The inverse of the radius of the circle equals the curvature in radians / m.
- The maximum deviation of the cantilever from horizontal was 0.06 radians, and so no mathematical or mechanical correction for rotation of the cantilever was implemented.
- Notice that the formula involves the use of the exponential function, and that the angles must be in radians.
- Given that the field oscillates at 60Hz, this gives me a phase angle of 0.4PI radians between samples.
