Chapter 3 Indefinite Integration Ex 3.2(C)

I. Evaluate:

Question 1.

Question 2.

Question 3.

Question 4.

Question 5.

7x + 3 = A(2 – 2x) + B
∴ 7x + 3 = -2Ax + (2A + B)
Comparing the coefficient of x and constant on both the sides, we get
-2A = 7 and 2A + B = 3

Question 6.

Solution:

Comparing the coefficients of x and constant term on both sides, we get

Question 7.

Solution:

Question 8.

Solution:

Question 9.

Solution:
