Chapter Overview
This chapter extends the concepts of trigonometry learned previously and focuses on their practical applications. It primarily deals with using trigonometric ratios to find the height or distance of an object when the angle of elevation or depression is known.
Important Keywords
- Angle of Elevation: The angle between the line of sight and the horizontal when the object is above the observer.
- Angle of Depression: The angle between the line of sight and the horizontal when the object is below the observer.
- Line of Sight: The straight line along which an observer looks at an object.
- Trigonometric Ratios: Ratios such as sin, cos, tan used to relate angles and side lengths in right triangles.
