Introduction
This section looks at the trigonometric functions from a right triangle perspective. The ratios of the three sides are used to define the six trigonometric functions.
Let's start by looking at a visual representation of these functions. You'll do this using Geogebra: Six Trigonometric Ratios.
Following successful completion of this lesson, students will be able to...
- Evaluate trigonometric functions of acute angles
- Determine the value of trigonometric functions for special angles
- Use the reciprocal identities and quotient identities
The above objectives correspond with the Alabama Course of Study: Precalculus standards: 29.
