12. Applications of Trigonometry

Applications of Trigonometry explain how trigonometric ratios are used to solve practical problems involving heights and distances. In this chapter, students learn about important concepts such as the angle of elevation and angle of depression, which are formed when an observer looks upward or downward at an object.

 

Using trigonometric ratios like sin, cos, and tan, students can calculate the height of buildings, towers, trees, or mountains without measuring them directly. These methods are widely used in fields such as surveying, navigation, engineering, and architecture. This chapter shows how trigonometry helps solve real-life measurement problems in a simple and scientific way.
