Which of the following are solutions to 2tanx/1-tan^2x=sqrt 3?
2 answers:
The other answer is incorrect
Answer:
A, D
Step-by-step explanation:
(1)
Assume that tan x = y. Replace this into the equation (1), we have:
+) 
=> 2y = 
=> 
=> 
=> 
=> 
=> 
=>
or 
If
=> y = - √3
=> tan x = - √3
=> x =
+ n.
with n is an integral
If 
=> y = 1/√3
=> tan x = 1/√3
=> x =
n is an integral
So that A, D are answers.

Answer:4th answer
Step-by-step explanation:
if width=w
Length =2w+1
Area =length *breadth
36=w(2w+1)
36=2w^2+w
0=2w^2+w-36
(-36)/(-8)=36/8=4.5
(-)/(-)=(+)
