This course extends the study of trigonometry that was begun in Geometry. The study of trigonometry is extended to triangles beyond right triangles and to circular functions. The graphs of all six trigonometric functions and their inverses will be included. This course prepares students for college placement tests and post-secondary study in any technical field. Technology is an integral part of this course and a TI83+ graphing calculator will be required. The topics in this one semester class are also included in the second semester of Precalculus. A TI83+ and TI84 graphing calculator is required.
