Question

If (1+cos 2x)/(sin 2x) +3[1+tanx.tanx/2] sin x =4 . Then value of tan x is equal to:-
A) 1
B) 1/2
C) 3
D) 1/3
It is a multiple correct question .​

Answer 1

Answer:

the answer is option A and D

Step-by-step explanation:

Answer 2

Please find above attached images

they contain step by step explanation

basic idea

evaluate the expression by putting values of sin2x,cos2x and six( in terms of tan)

then keep on solving

then arrive at value of cos2x

then replace cos 2x in terms of tan

then get a quadratic equation with variable in tan

then find both roots.

both the roots come out to be 1 and 1/3
