Solving Real-Life Problems with Trigonometry

Apply your knowledge of trigonometry to solve real-life problems like determining the height of a building, the distance to a distant object, or the angle of elevation of a slope.

Calculating Distance with Trigonometry

In real-world navigation, you can use the Pythagorean theorem to find the distance between two points. If you only know the angles and the distance to one point, use sine, cosine, or tangent to find the other distances.

Understanding Trigonometric Ratios

To begin, recall the trigonometric ratios sine, cosine, and tangent from your secondary 3 math syllabus. These are essential for navigation problems. Sine relates to the opposite side over the hypotenuse, cosine to the adjacent side, and tangent to the opposite divided by the adjacent side.

Finding Bearings and Directions

To find the direction or bearing from one point to another, use the inverse sine, cosine, or tangent functions. These will give you the angle in degrees or radians, which can be converted to a cardinal direction.

Navigating with Triangulation

Triangulation is a method used to find the location of a point by measuring the angles to it from two known points. This technique is widely used in real-world navigation, including GPS systems.
