RD Sharma Chapter 11 Class 10 Maths Exercise 11.2 Solutions

RD Sharma Chapter 10 Class 11 Maths Exercise 11.2 Solution – Trigonometric Identification is compiled to give you a clear idea of ​​the chapter. Chapter 6 explains various equations including trigonometric ratios of an angle, also known as trigonometric identities. Here a trigonometric identity is first proved and then used to prove another trigonometric identity. Trigonometric identities provide different relationships between trigonometric ratios sin cos, cos ities, sec θ, csec θ, tan the and cott the for different angles.

RD Sharma Chapter 10 Class 11 Maths Exercise 11.2 Solution: This exercise consists of 12 questions. Questions 1 and 2 ask you to find the other trigonometric ratios for an angle when the trigonometric ratios of an angle are already given. Through questions 3 to 7 you are asked to find the value of the corresponding equations when the value of the corresponding trigonometric ratio is given.

Important Definition for RD Sharma Chapter 11 Class 10 Maths Exercise 11.2 Solutions

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.
