Trigonometric Functions Review: Identifying and Solving Problems with SOH CAH TOA

This review covers how to identify and make use of the SOH CAH TOA relationships in trigonometry based on given angles and sides of right triangles. Practice deciding which function (sine, cosine, or tangent) to use when given specific values such as angles and adjacent/hypotenuse or opposite sides. Learn how to round your results to the nearest tenth. This comprehensive guide includes visual aids to help understand the concepts better and solve problems effectively.
