Radian
This is the SI unit of (supplementary ) plane angle. One radian is the plane angle between two radii of a circle which cut off on the circumference of an arc equal to the length of the radian..

Definition of sin
- 1 x For x [-1, 1], if q is an angle whose sine is x, then we say that sine inverse x is q and write sin -1 x = q . For practical purposes, only principal values of sin - 1 x are considered. sin -..
