This Inverse Trig lesson plan also includes:
Use this complete lesson plan to introduce geometers to inverse trigonometric functions. Learners use trigonometric ratios to solve triangles when an angle measure is known, then explore using the inverse process when only side lengths are given. The exploration naturally leads to a discussion about use of the inverse trigonometric function keys on the calculator. The instructional activity also includes five practice problems, three of which are real-world scenarios. Each practice problem has multiple parts.
