Question
∫ log 
dx is equal to
dx is equal toOptions
A.log2(tanx - x) + c
B.log2
+ c
+ cC.2log2 + c
+ cD.log(tanx - x) + c
Solution
I = ∫ log(tan x - x)
dx
Put log(tanx - x) = t
⇒ I = ∫ t dt =
+ c
⇒ I =
log2(tan x - x) + c
dx Put log(tanx - x) = t
⇒ I = ∫ t dt =
+ c⇒ I =
log2(tan x - x) + cCreate a free account to view solution
