If 
+ 
= 
, then
A
tan 2 x = 
B
+ 
= 
C
tan 2 x = 
D
+ 
= 
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a,b)
+ 
= 
⇒ 
+ 
= 
⇒ 
+ 
= 
⇒ 5 sin 4 x – 4 sin 2 x + 2 = 
⇒ 25 sin 4 x – 20 sin 2 x + 4 = 0 ⇒ (5 sin 2 x – 2) 2 = 0
⇒ sin 2 x = 
, cos 2 x = 
⇒ tan 2 x = 
and 
+ 
=
