Question

Range of
the
function: F(x)= 1-tanx/1+tanx

Answer 1

one is the required value

Answer 2

Answer:

range is R

Step-by-step explanation:

Put  1 = tan ( π /4 )

You will observe that its the formula of tan(A-B).

Simplifying it, you wil have :-

1 − tan x /1 + tan x = tan ( π/ 4 + x )

So the function is now reduced to  tan θ .

And Range of  tan θ  is  R .

Hence the answer is (-infinity,+infinity)

Hope it helps :)
