Finding Lengths in Right Triangles: Introducing the Secant Ratio

The video tutorial introduces the concept of trigonometric ratios, focusing on the secant ratio. It explains how the secant ratio is the reciprocal of the cosine ratio and is used in right triangles to compare the hypotenuse to the adjacent leg. The tutorial provides examples of calculating the secant ratio in various triangles and emphasizes that it is only applicable in right triangles. The video concludes with a problem-solving example using the secant ratio to find a segment length without using the cosine ratio.
