Question

What is the rules of degree change

Answer 1

radian to ° =180/π
as viceversa.

Answer 2

degree to radian ........
= pi × degree angle /180
eg. 60 ° = pi * 60 / 180 = pi / 3 radian.

radian to degree
= 180 × radian measure /pi
eg . 2pi radian = 2pi × 180 / pi = 2×180 = 360°......that's it...
