Here is a basic plan for the beginning teacher to use for introducing the class to the right triangle trigonometric functions. It outlines the instructional activity objectives, class procedures, and basic instructional techniques...

Students explore the concept of the six trigonometric functions, places where the functions can be utilized, and apply these functions to several electrical application problems.

Students investigate the basic trigonometric functions.  In this geometry/trigonometry lesson, students explore strategies to solve right triangles using basic trigonometric functions.  The lesson includes an application...

Students find the identity o sine, cosine and tangent. In this precalculus lesson, students solve and identify the different parts of a right triangle. They use the ratios of the Pythagorean Theorem to find the missing side or angle.

Students identify the ratios of trig identities. In this geometry lesson plan, students solve the missing sides and angles of triangles using trig ratios. They relate the graphs and waves to real life scenarios.
