Unit circle trigonometry definitions of the six trigonometric functions definitions of the six trigonometric functions we will soon learn how to apply the coordinates of the unit circle to find trigonometric functions, but we want to preface this discussion with a more general definition of the six trigonometric functions. And the whole point of what i'm doing here is i'm going to see how this unit circle might be able to help us extend our traditional definitions of trig functions.
