Cách sử dụng
Radian is a unit used to measure angles. It tells us how much of a circle we are talking about. So, if you are talking about a quarter of a circle, that is 90 degrees or pi/2 radians. If you are talking about half a circle, that is 180 degrees or pi radians. Radians are used a lot in math and science, especially when dealing with things like waves and oscillations.
