SOLUTION: Find sin x/2, cos x/2, and tan x/2from the given information. sec x = 9/8, 270� < x < 360�

Question 1131784: Find sin x/2, cos x/2, and tan x/2from the given information. sec x = 9/8, 270� < x < 360�
Answer by MathLover1(20850) (Show Source): You can put this solution on YOUR website!
Find , , and from the given information:

, � < < �

(in quadrant IV where )

Identities you need to use:
= �

choose positive root because is in quadrant II where
= �

= �

choose negative root because is in quadrant II where

How to check answers with calculator:

≈ radians ≈� (reference angle in specified quadrant IV)

standard position of angle=�
�

reference angle=�

≈.......(in quadrant II where )
and above we have
.....which confirms our solution

you can check and tan in the same way
