The aim of this topic is to develop the ability to draw clear diagrams in two dimensions and to apply appropriate geometric and trigonometric techniques to problem-solving in two and three dimensions.
Pythagorean theorem
trigonometry
Trigonometry is widely used in science, engineering, map-making and navigation. The earliest references to trigonometry are found in Indian Mathematics.
Trigonometry is used in construction when working with angles of elevation and angles of depression, and in navigation when using bearings.
