Solve for x in (0 ; 360) : 2 tan x - 1 = -tan (-x).

Expert Answers

An illustration of the letter 'A' in a speech bubbles

We have to solve 2 tan x - 1 = -tan (-x)

Now we know that tan -x = - tan x

2 tan x - 1 = -tan (-x)

=> 2 tan x - 1 = tan (x)

=> tan x - 1 = 0

=> tan x = 1

=> x = arc tan 1

=> x = 45 degrees and 225 degrees.

The required values of x = 45 degrees and x = 225 degrees
