NCERT Solutions Class 10 Maths Chapter 8 Exercise 8.4 Introduction to Trigonometry
NCERT solutions for class 10 maths chapter 8 exercise 8.4 Introduction to Trigonometry targets one of the most important sections of this chapter on trigonometric identities. It not only carries the maximum weightage in board exams but simplifies solving problems several fold. An equation involving trigonometric ratios of an angle is called a trigonometric identity if it is true for all values of the angles involved. These identities will make their way throughout the remainder of a child’s school career. The NCERT solutions exercise 8.4 class 10th has a total of 5 questions with subparts that are based on proving expressions using the identities that kids have learned.
To solve NCERT solutions of ex 8.4 class 10th, students must revise all the concepts from the previous three exercises. A fun fact to note is that using these identities, we can express each trigonometric ratio in terms of other trigonometric ratios, i.e., if any one of the ratios is known, we can also determine the values of other trigonometric ratios.

What is Class10 Maths Ex 8.4 All about?
Class 10 maths ex 8.4 is all about trigonometric identities. The basic trig identities are cosec A = 1/sin A; sec A = 1/cos A; cot A = 1/tan A; sin2A + cos2A = 1; cosec2A - cot2A = 1; sec2A - tan2A = 1. Using these identities, we have to establish/prove the given identities in exercise 8.4 of class 10.
