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.

Radians are used to find the properties of a circle and they form the circumference of a circle with a length of the same length of the circle's radius.
