# NCERT Solutions for Class 10 Maths Chapter 8 Introduction to Trigonometry - PDF Download

NCERT solutions for class 10 maths chapter 8  Trigonometry is based on the fundamental concept of the right triangle and provides students with an introduction to trigonometry. In this chapter, there are two main topics that students will be learning about: trigonometric ratio and trigonometric identities. NCERT solutions class 10 maths chapter 8 helps the students to understand the trigonometric function used in the equation. Chapter 8 of the NCERT solutions class 10 maths is based on formulas, so it's a good idea to make a formula chart since there are many formulas related to trigonometry. A right-angled triangle has six trigonometric ratios. These ratios are sine, cosine, tangent, cosecant, secant, cotangent. These solutions will be perfect guidelines that a student can follow to create a very solid conceptual basis for these ratios.

NCERT solutions for class 10 maths chapter 8 introduction to trigonometry helps the students to understand the concepts and score well in the class 10 board examination. Students are able to resolve their doubts and gain a thorough understanding of the concepts in this chapter. NCERT solutions are expert-curated and provide step-by-step answers to the questions. You can also download these NCERT solutions free pdf provided by eSaral.

## Important Topics covered in Chapter 8 - Introduction to Trigonometry

NCERT solutions for class 10 maths chapter 8 Introduction to Trigonometry discusses the following topics:

 8.1 Introduction 8.2 Trigonometric Ratios 8.3 Trigonometric Ratios of Some Specific Angles 8.4 Trigonometric Identities

8.1 Introduction - In this section, you will study some ratios of the sides of a right triangle with respect to its acute angles, called trigonometric ratios of the angle. We also specify the trigonometric ratios of angle 0o and angle 90o. Trigonometric ratios for certain angles will be determined, and certain identities associated with these ratios will be established. These identities are referred to as trigonometric identities.

8.2 Trigonometric Ratios - Here, we define certain ratios involving the sides of a right triangle, and call them trigonometric ratios. Different functions of trigonometry are used to explain the topic with appropriate examples.

8.3 Trigonometric Ratios of Some Specific Angles - In Geometry, you’ve already learned how to construct angles 30 degree, 45 degree and 60 degree, and 90 degree. Here, we’ll find the trigonometric ratios for these angles, as well as 0 degree. It explains Trigonometric Ratios of 45o, Trigonometric Ratios of 30o and 60o, Trigonometric Ratios of 0o and 90o with suitable examples.

8.4 Trigonometric Identities - You may recall that an equation is called an identity when it is true for all values of the variables involved. Similarly, a trigonometric identity is just like an equation that has trigonometric ratios for an angle, If all the angles involved are equal to a certain value. In the following section, we’ll demonstrate one trigonometric identity and apply it to prove other helpful trigonometric identities.
