The name cosinus originated with Edmund Gunter. Revision books are also available to download. Description, history and identities related to Trigonometry is given below. What is Trigonometry? Why is trigonometry a useful tool in astronomy? What is the objective of Class 10 Trigonometry? An equation involving trigonometric ratios of an angle is called a trigonometric identity, if it is true for all values of the angle s involved.

Solution: Ex 8. Solution: Class 10 Maths Introduction To Trigonometry Trigonometry Trigonometry is the study of relationships between the sides and angles of a right-angled triangle. Trigonometric Ratios Trigonometric ratios of an acute angle in a right triangle express the relationship between the angle and the length of its sides.

Trigonometric Identities An equation involving trigonometric ratios of an angle is called a trigonometric identity, if it is true for all values of the angle s involved. Trigonometry is the study of relationships between the sides and angles of a triangle. Long ago, ancient Greek and Indian astronomers used these handy techniques to measure the distances of stars and planets from the Earth very precisely.

Even today, most of the technologically advanced methods used in Engineering and Physical Sciences are based on trigonometrical concepts. This branch of Mathematics, called Trigonometry is extremely helpful in dealing with height and distances which are not easy to measure.

In this chapter, you will first study the ratios of sides of a right triangle concerning its acute angles and see how these ratios only depend on the measure of the angles involved. You will then go through the names and definitions of these six trigonometric ratios of an angle.
