The radian is the standard unit of angular measure, used in many areas of mathematics.
The radian is the standard unit of angular measure, used in many areas of mathematics.
It is a central angle that corresponds to an arc that has the same length compared to a semi-diameter.
The unit circle has arcs and semi-diameters that have the same length which are important to easily understand what radian is.
The formula for an arc is rθ. θ is radian and the arc is part of circumference of a circle.
1 rad= 180/pie
I prefer degrees because I hate approximate value. And I am used to degrees. I think the standard of mathematical pureness is dependent upon accuracy. So It seems to me that degrees are purer than raidans.
