Exercise 19.20 Page No: 19.106
Evaluate the following integrals:
Solution:
Solution:
⇒ 1 = (A + B) x + (3A – 2B)
⇒ Then A + B = 0 … (1)
And 3A – 2B = 1 … (2)
Solving (1) and (2),
2 × (1) → 2A + 2B = 0
1 × (2) → 3A – 2B = 1
5A = 1
∴ A = 1/5
Substituting A value in (1),
Or I = log|(x – 2)/(x + 3)| + x + c
Solution:
