In this video, NCERT Class 11 Maths Chapter 3 Exercise 3.4 Q8, Q9 | Exercise Solution, we are giving solution to question 8 and question 9 of chapter 3.4 of Class 11 Mathematics. This exercise deals with using trigonometric functions to prove some trigonometric identities. Chapters : 0:00 : Introduction 01:56 : Question 8 06:45 : Question 9 Video Highlights: 1. In this video, we have solved Q8 & Q9 of Trigonometry Exercise 3.4. 2. Q8 deals with finding general solutions of sec2 2x=1–tan2x 3 Q9 deals with finding general solutions of sin x + sin 3x + sin 5x = 0 These question use some of the formulae which are required to solve this problem : 1. Sinx= Siny implies x=nπ+(–1)^n y, where n∈Z 2. cos x = cos y, implies x= 2nπ ± y,where n ∈ Z 3. if x and y are not odd multiple of 2 , then tan x = tan y implies x = nπ + y, where n ∈ Z To see more on Trigonometry for Class 11 check below videos from this channel : 1. • Can you solve this in 10 seconds? |Trigono... : Can you solve this in 10 seconds? |Trigonometry Trick Question | Trigonometry CBSE Class 11 2. • Trigonometry | Find the value of expressio... : Trigonometry|Find the value of expression tan1°*tan2*..*tan89° 3. • CBSE Class 11 Mathematics Exercise 3.2 Cha... : CBSE Class 11 Exercise 3.2 Chapter 3 Q1 and Q2 | NCERT Exercise 3.2 Solution Q1 & Q2 4. • CBSE Class 11 Mathematics| Solution to NCE... : CBSE Class 11 Mathematics| Solution to NCERT Mathematics Class 11| Exercise 3.2 Chapter 3 Q3, Q4, Q5 5. • How to Solve CBSE Class 11 Exercise 3.2 Ch... : How to Solve CBSE Class 11 Exercise 3.2 Chapter 3 Q6, Q7, Q8, Q9, Q10 | NCERT Solution Exercise 3.2 Your queries : CBSE Class 11 Maths Chapter 3 Exercise 3.4 Q8, Q9 | NCERT Chapter 3 Exercise 3.4 Solution Check out my website for Free Mathematics Course - https://shiwamsclass.com/courses/math... #cbseclass11thmaths #trigonometryclass11 #Exercise3.3 ~-~~-~~~-~~-~ Please watch: "Mastering Trigonometry : Comprehensive Guide to Trigonometric Functions and Identities" • Mastering Trigonometry : Comprehensive Gui... ~-~~-~~~-~~-~
