What is the relation between Degrees and Radians?


A Circle of Radius r has a Circumference of 2πr,a Circle of radius 1 unit has circumference 2π.When ɵ is a complete rotation,P travels the Circumference of an unit circle completely.

If ɵ is a complete rotation then ɵ =2πradian.onthe other hand we already know that one complete rotation is 360o,Consequently,360o=2π radians or 180o=π radian.It Follows that 1o=π/180 radian and 180o/π=1 radian.Therefore 1o=0.01746  approximately radian and 1 radian=180ox7/22=57o16' approximately.
