What radians and degrees actually measure
Radian (rad) — A radian is the angle where the arc equals the radius. A full turn is 2π radians. Calculus, physics and programming — every trig function assumes radians.
Degree (°) — A degree is 1/360 of a full turn, a division inherited from Babylonian astronomy. Geometry, navigation and construction.
