Indefinite IntegrationHard
Question
The value of 
dx is equal to
dx is equal to Options
A.2 sin x - ln |sec x + tan x| + C
B.2 sin x - ln |sec x - tan x| + C
C.2 sin x + ln |sec x + tan x| + C
D.None of these
Solution
I = 
dx = 
dx = 2 sin x - ∫sec x dx = 2 sin x - ln |sin x + tan x| + C
dx = dx = 2 sin x - ∫sec x dx = 2 sin x - ln |sin x + tan x| + CCreate a free account to view solution
