Exercise 8.4 of class 10 maths recalls the concept of trigonometric identities. In this exercise, a trigonometric identity is defined as an equation which involves the trigonometric ratios of an angle when it is true for all the values of the angle involved in a right angle triangle. With the help of trigonometric identities, the expression of one trigonometric ratio is written in terms of other trigonometric ratios. By finding one trigonometric identity of cos and sin function, the trigonometric identities of other functions are easily found since the functions are inter-related to each other and the proofs are given elaborately.

In this chapter, trigonometric ratios are expressed in terms of other ratios, proving the trigonometric expressions and justifications with respect to the trigonometric identities are given and also refer NCERT solutions for class 10 maths chapter 8 to solve more problems to score more in the examinations.
