AP EAMCET · Maths · Indefinite Integration
If the primitive of is , then which among the following is true?
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Primitive means integration ⇒∫coslogxdx=fxcosgx+sinhx ⇒I=∫coslogxdx By parts formula ∫u·v dx=u∫v dx-∫ddxu∫vdxdx ⇒I=∫1.coslogxdx ⇒I=coslogx·x-∫-sinlogxxx dx…
