🔍 Chapter Overview: Some Applications of Trigonometry
Chapter 9 introduces students to the practical applications of trigonometry, especially in solving problems related to heights and distances. It builds on basic trigonometric concepts and applies them to real-world scenarios.
Key Concepts Covered:
- Trigonometric Ratios: sine (sin), cosine (cos), tangent (tan)
- Angle of Elevation: Angle formed when looking up at an object from the horizontal
- Angle of Depression: Angle formed when looking down at an object from the horizontal
- Right Triangle Applications: Using trigonometric ratios to find unknown sides or angles
📘 Trigonometric Ratios in Right Triangle ABC (∠C = 90°)
Let’s recall the basic definitions:
- sin A = Opposite / Hypotenuse = BC / AB
- cos A = Adjacent / Hypotenuse = AC / AB
- tan A = Opposite / Adjacent = BC / AC
These ratios are used extensively to solve problems involving vertical and horizontal distances.
