Indefinite IntegrationHard
Question
The value of
dx is equal to
dx is equal toOptions
A.2 ln 
+ C
+ CB.ln + C
+ CC.-2 ln + C
+ CD.none of these
Solution
I = 
dx = 
put √2 cos 
= t ⇒ sin 
dx = - √2 dt
⇒ I = - 2
= - 2ln
- 2ln
+ C1
= - 2 ×
ln 2 - 2 ln 
+ C1
= - 2 ln
+ C
dx = put √2 cos = t ⇒ sin dx = - √2 dt⇒ I = - 2
= - 2ln
- 2ln
+ C1 = - 2 ×
ln 2 - 2 ln + C1= - 2 ln
+ C Create a free account to view solution
