RS Aggarwal Class 11 Solutions Chapter-16 Conditional Identities Involving the Angles of a Triangle

Conditional Identity

Conditional Identity is a part of Trigonometry, and it basically deals with the special cases that are covered under trigonometry. The identities help to know the relationship between the angles of a triangle. The chapter involves sines and cosines, and it also involves the square of sines and cosines, there are sums that involve tangents. This chapter focuses on the various ways to use trigonometry to identify the relationship between the angles of a triangle. Here we have briefed the whole chapter, which would help the students in the times of their examinations. We have also provided certain important questions to make the students acquainted with the examination pattern. Here are some of the important formulas to be used in the chapter on conditional identities:

• Sin x + Sin y = 2 sin (x+y/2) cos (x-y/2)

• Sin x - Sin y = 2 cos (x+y/2) sin (x-y/2)

• Cos x + Cos y = 2 cos (x+y/2) cos (x-y/2)

• Cos x - Cos y = - 2 sin (x+y/2) sin (x-y/2)

The type of questions that the chapter covers involve the following:

• To prove the trigonometric equation when the measurement of the angles of the triangles is given.

• To prove the trigonometric equation using a formula when the angles of triangles are given.

• To prove the trigonometric equations involving identities.

Exercise 16 of Chapter 16 Class 11 has a total of 12 sums, and here on our website, we have provided the solutions to each one in an orderly manner. This solution will help the students to excel in their studies and secure better grades. Most importantly, the solutions are prepared as per the latest guidelines of NCERT and the CBSE board.
