Solution: We know that so, we know, if I = then I = 2I = l=Ï€ Question 2. Solution: We know that So, if I = then I = 2I = 2I= 2I = 2I=0 I=0 Question 3. Solution: We know So, if I= then I= So 2I= 2I = 2I= 2I=Ï€/6 I=Ï€/12 Question 4. Solution: We know So, if I = then, I = 2I = 2I = 2I = 2I=Ï€/6 I=Ï€/12 Question 5. Solution: We know so, if then, we know if f(x) is even f(x) is odd Here, f(x) = tan2x which is even hence, I = Question 6. Solution: We know So, if, then So, Question 7. Solution: We know Hence, if, then so, Question 8. Solution: We know hence, if Then, So, Question 9. Solution: if f(x) is even if f(x) is odd here, is odd and is even Hence, 2 Question 10. Solution: if then, Question 11. Solution: let, we know that, hence, Question 12. Solution: Let, we know that , so, then, Question 13. Solution: We know that, So, then, I Question 14. Solution: We know that, so, then, Question 15. Solution: We know that, Let, hence, Question 16. If f(a+b-x)=f(x), then prove that Solution: Like Article Suggest improvement Previous Class 12 RD Sharma Solutions - Chapter 20 Definite Integrals - Exercise 20.3 | Set 2 Next Class 12 RD Sharma Solutions- Chapter 20 Definite Integrals – Exercise 20.4 Part B Share your thoughts in the comments Add Your Comment Please Login to comment...
