deg2rad() function
Degrees and Radians are units of measuring angles.A degree is a measure of angle equal to 1/360th of a revolution, or circle.The number 360 has 24 divisors, making it a fairly easy number to work with. There are also 360 days in the Persian calendar year, and many theorize that early astronomers used 1 degree per day. A radian is the measurement of angle equal to the start to the end of an arc divided by the radius of the circle or arc.

Understanding the Main Trigonometric Functions
In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are functions of an angle. They relate the angles of a triangle to the lengths of its sides. Degrees and Radians are units of measuring these angles. Degrees originated as an unit to measure how far constellations moved in a day (1 degree ~ 1 day of movement). Degrees measure angles by how far we tilted our heads(Observer's view point). Radians measure angles by distance traveled(Movers's view point).
