### 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).
