Indefinite IntegrationHard
Question
If
= I tan-1 
+ C then :
= I tan-1 + C then :Options
A.I = 2/3
B.m = 1/3
C.I = 1/3
D.m = 2/3
Solution
Let I = 
= I tan-1 + C
Put tan x/2 = t ⇒ sec2 x/2 dx = 2dt
⇒ I = 2
+ C ⇒ I = 
, m = 
= I tan-1 + C Put tan x/2 = t ⇒ sec2 x/2 dx = 2dt ⇒ I = 2
+ C ⇒ I = , m = Create a free account to view solution
