Whenever you are not able to use degrees you use radians instead

Wherever you want to measure and calculate angles you can use radians

Scroll down to related links and use the fine calculator "Convert radians to degrees and degrees to radians".

That's a simple way to measure angles, but later on in Calculus radians are used. 2π radians = 360o.

When people use degrees, they either use "degrees" as in 30 degrees, or the little circle as in 30o. For Radians, they might say radians or possibly R or Rad.
