Trigonometric Functions and Ratios

In this video, the teacher explains how to solve for missing parts of right triangles using the trigonometric ratios SOH CAH TOA. The video includes two examples: one using the sine ratio to find the opposite side when the hypotenuse is known, and another using the tangent ratio to find the opposite side when the adjacent side is known. The teacher provides step-by-step instructions, including how to use a calculator for trigonometric calculations. The video concludes with a practice problem for viewers to solve on their own.
