# Defining Circular Functions

## Use the graph to determine the six trigonometric functions.

Which segment represents the sine of angle BAC?

Which segment represents the cosine of angle BAC?

## Tangent and Secant Lines

Use the properties of reciprocals (4 > 3, but 1/4 < 1/3) and the definitions of tangent and secant lines to determine the answers to the following:

Which segment represents the tangent of angle BAC?

Which segment represents the cosecant of angle BAC?

Which segment represents the secant of angle BAC?

Which segment represents the cotangent of angle BAC?
