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
