An angle subtended by an arc equal to the radius.
2π2\pi2π radians equal a full angle of 360360360 degrees.
Radians = Degrees × π180\frac{\pi}{180}180π.
Degrees = Radians × (180/π)(180/\pi)(180/π).
s=rθs = r\thetas=rθ, where rrr is radius and θ\thetaθ is in radians.
A = (1/2)r²θ, where r is radius and θ is radians.
π6\frac{\pi}{6}6π radians.
π2\frac{\pi}{2}2π radians.
Used in trigonometry, physics, and circular motion.
More natural for derivatives/integrals of trig functions.
