Trigonometric Ratios

This lesson covers the identification of sine, cosine, and tangent of an acute angle. It explains how to apply these trigonometric ratios to solve problems involving distances and lengths in right-angled triangles. The relationship between the sides and angles of triangles is also discussed.

• 05:55 “over adjacent? Your opposite is what? Your opposite already given to be what? 12. Don't forget. That will give you what? 12. What's your adjacent? 16. So in a simplified fraction. I have three here. Four can go. Successf...”
