TRIGONOMETRY
The word ‘trigonometry’ means ‘triangle measurement’. Trigonometry is an important tool for evaluating measurements of height and distance. It plays an important role in surveying, navigation, engineering, astronomy and many other branches of physical science. Trigonometry involves the ratios of the sides of right triangles. The three ratios are called tangent, sine and cosine.
