Radians are the preferred measurement unit in more advanced mathematics because of some of its properties. The basic definition is also simple: if you take the radius of a circle and wrap it around its circumference then that arc will subtend an angle of 1 radian at the centre of the circle.
Some useful properties for angles measured in radians:
sin(x) = x - x3/3! + x5/5! - x7/7! + ... and
cos(x) = 1 - x2/2! + x4/4! - x6/6! + ... .
The limit of sin(x)/x as x tends to zero is 1, so that the derivative of sin(x) is cos(x) and so on. Derivatives and integrals of sine and cosine functions are of enormous importance in mathematics.
