A
a = 
, b ∈ R
, b ∈ R
B
a = –

, b ∈ R
C
a = 
, b ∈ R
, b ∈ R
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
B
∫ (sin 2x – cos 2x) dx = 
sin (2x – a) + b
⇒ 
dx
= 
sin (2x – a) + b
⇒ – 
dx
= 
sin (2x – a) + b
⇒ – 
(2x + π /4) dx = 
sin (2x – a) + b
⇒ – 
sin (2x + π /4) + c = 
sin (2x – a) + b
⇒ 
sin 
+ c = 
sin (2x – a) + b
∴ a = – 
, b ∈ R.
