Trigonometry isn’t just a set of formulas—it’s a powerful tool that helps us solve real-world problems involving distances and angles. Here’s a simple breakdown of some common applications:

1. Applications of Trigonometry:
 • Trigonometry deals with the relationships between the sides and angles of triangles.
 • It helps us calculate unknown distances or heights when we know some sides and the angles.
 • It’s used in fields such as engineering, navigation, architecture, and even computer graphics.

2. Solving Bearing Problems:
 • A bearing is a way to describe direction, usually measured in degrees clockwise from North.
 • For example, when a pilot is navigating, they might use bearings to chart a course from one airport to another.
 • In a bearing problem, you often know the direction and distance traveled, and you need to find your position relative to the starting point.
 • Trigonometry helps break the movement into north-south and east-west components using sine and cosine functions.

3. Finding the Angles of Elevation and Depression:
 • The angle of elevation is the angle between the horizontal line and your line of sight when looking up.
 • The angle of depression is measured from the horizontal when looking down.
 • For instance, if you stand at a distance from a building and measure the angle of elevation to its top, you can calculate the building’s height using trigonometric ratios.
 • Similarly, if you’re looking down from a cliff and measure the angle of depression to a point below, trigonometry helps determine how far that point is from the base of the cliff.

4. Simple Three-Dimensional Problems:
 • Many real-world problems involve three dimensions, like finding the shortest distance between two points in space or calculating the slope of a roof.
 • In these cases, you often apply trigonometric principles along with the Pythagorean theorem.
 • For example, using angles and distances along different directions, you can determine the height, width, or depth of a three-dimensional object.
 • Trigonometry in three dimensions might involve working with right-angled triangles in different planes, and sometimes you may use concepts of spherical trigonometry if dealing with curved surfaces like the Earth.

By breaking complex shapes into simpler triangles and using known values (like an angle or a side), you can solve many practical problems. Whether it’s navigating a ship using bearings, finding the height of a building with an angle of elevation, or solving a three-dimensional puzzle, trigonometry provides the formulas and techniques needed to get answers clearly and efficiently.
