FAQs on RS Aggarwal Class 11 Solutions Chapter-16 Conditional Identities Involving the Angles of a Triangle
1. What is Conditional Identity?
Conditional Identity is a part of trigonometry that deals in the exceptional cases of trigonometry involving triangles. The conditional Identity is used to prove the relationship between the angles of a triangle. They involve sums on sines and cosines, squares of sines and cosines, and sums on tangents. Basic knowledge about trigonometric ratios and the related identities and formulas must be acquired to understand conditional trigonometric identities better. In other words, a conditional identity holds true if the variables satisfy a given condition.
2. What are the formulas used in Conditional Identities?
In Chapter 16 ‘Conditional Identities Involving the Angles of a Triangle’ of Class 11 RS Aggarwal, the questions are based on the concept of solving trigonometric equations using conditional identities. There are basically four formulas that are used in the chapter conditional identities, and they are:
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)
