# 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 class 10 maths chapter 8 exercise 8.4 has a total of 5 questions with subparts that are based on proving expressions using the identities that kids have learned.

In order to solve NCERT solutions class 10 maths chapter 8 exercise 8.4, 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.
