Let’s talk about Conditional Identities in more detail
Conditional Identity is a part of trigonometry, and it mostly deals with the special cases that trigonometry covers. The identities help you figure out how the angles of a triangle connect to each other. There are sines and cosines in this chapter, as well as the squares of sines and cosines. Tangents are also used in some sums.
This chapter is about the different ways to use trigonometry to figure out how the angles of a triangle relate to each other. Here, we’ve given a short summary of the whole chapter, which will help students do better on their tests. We also gave the students some important questions to help them understand how the test will be set up. Here are some important formulas to use 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)
This Chapter talks about the following kinds of questions:
- To show that the trigonometric equation is true when the angles of the triangles are already known.
- When the angles of triangles are given, use a formula to show that the trigonometric equation is true.
- To show that the identities in the trigonometric equations are true.
Exercise 16 of Chapter 16 of Class 11 has a total of 12 sums, and we have put the answers to all of them in order on our website. This answer will help students do better in school and get better grades. Most importantly, the solutions are made according to the most recent NCERT and CBSE guidelines.
FAQ ( Frequently Asked Questions )
1. What’s Conditional Identity?
Ans – Trigonometry has a part called “conditional identity” that deals with triangles that don’t fit the normal rules. The conditional Identity is used to show how the angles of a triangle fit together. They include adding up sines and cosines, adding up the squares of sines and cosines, and adding up tangents. To understand conditional trigonometric identities better, you need to know the basics about trigonometric ratios and the identities and formulas that go with them. In other words, a conditional identity is true if the variables meet a certain condition.
2. What are the formulas that Conditional Identities uses?
Ans – In RS Aggarwal Class 11 Solutions Chapter 16, “Conditional Identities Involving the Angles of a Triangle,” the questions are based on the idea that conditional identities can be used to solve trigonometric equations. In the chapter “Conditional Identities,” there are basically four formulas that are used. 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 = 2cos (x+y/2) cos (x-y/2)
- Cos x – Cos y = -2 sin (x+y/2) sin (x-y/2)
3. What other study materials besides the RS Aggarwal Class 11 Solutions can you download from the Utopper site?
