RD Sharma Class 10 Maths Solutions Chapter 6 – Trigonometric Identities have been compiled in order to give you a fair idea of the Chapter. Chapter 6 explains the various equations involving Trigonometric Ratios of an angle, also known as Trigonometric Identities. Here one Trigonometric identity is proved first, and then it is used to prove further Trigonometric Identities. The Trigonometric Identities provide various relations between the Trigonometric Ratios Sin θ, Cos θ, Sec θ, Cosec θ, Tan θ, and Cot θ for different angles.

There are 2 exercises with 98 questions in RD Sharma Class 10 Maths Solutions for Chapter 6 – Trigonometric Identities, all of which have been meticulously solved by our team of subject matter experts. The solutions to the given questions are based on proving that the left-hand side equation is equal to the term given in the right-hand side. The questions in which there are fractional terms have been solved by a different approach. Here the denominator of the left-hand side term is rationalized by multiplying and/or dividing with suitable terms and then is equalized with right-hand side term.

The speciality of solutions for RD Sharma Class 10 Maths Trigonometric Identities lies in the fact that it provides a logical flow and gives you sufficient practice. This way, you can easily become thorough with the chapter and clear all your doubts. Our RD Sharma Solutions are clear, effective, and efficient. They help you increase your learning and revising speed during your Class 10 Board exams.

Class 10 Maths Trigonometric Identities: Important Topics

Class 10 Maths Trigonometric Identities teach you that an equation is called an identity when it is true for all values of the variables involved, and this chapter is based on equations involving Trigonometric ratios.

The components of the topic are given below.


  • Trigonometric Identities


This topic of trigonometry subject teaches you that 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. Using these Identities, we can express each Trigonometric ratio in terms of other Trigonometric ratios. If anyone of the ratios is known, we can also determine the values of other Trigonometric ratios.

Here you will also learn that any proved Trigonometric equation is called Trigonometric identity when it holds for all angles A such that 0° ≤ A ≤ 90°.

The Trigonometric Identities are –

sin2A + cos2A = 1,

sec2A – tan2A = 1 for 0° ≤ A < 90°,

cosec2A = 1 + cot2 A for 0° < A ≤ 90º.
