The Basics of Trigonometry I. Definitions An angle is formed by rotating a ray around its endpoint or vertex. The initial position of the ray is the initial side of the angle, while the location of the ray at the end of its rotation is the terminal side of the angle. If the rotation of an angle is counterclockwise, the angle is positive; if the rotation is clockwise, the B. c. angle is ...

An Introduction to Trigonometry P.Maidorn I. Basic Concepts The trigonometric functions are based on the unit circle, that is a circle with radius r=1. Since the circumference of a circle with radius r is C=2Br, the unit circle has circumference 2B. For any point (x,y) on the unit circle, the associated angle 2 can be measured in two different ways: 1. degree measure: in this case the ...
