Question

Tan theta equal to one by root 3

Answer 1

Step-by-step explanation:

Let theta = x ) , tan x = (3)^1/2

sin x / cos x = (3^1/2) /1

or sin x/ (3^1/2) = cos x / 1 = +/- (sin^2 .x+cos ^2. x )^1/2 / (3+1)^1/2

or sin x / (3^1/2) = cos x / 1 = +/- 1/2.

Therefore cos x = +/-(1/2).

Now 1 -cos x = 1 - (+/-1/2)

=(1 - 1/2 ) ,( 1 +1/2 )

= 1/2 , 3/2 . Answer.
