Question 523753
uestion:find two values of theta that saitisfy each of the equations below. Give your answers in radians
(0 < theta < or equal to 2 pi) 
a. sin theta = - sqrt ( 2 )/ 2 
b. sec theta = - 2 sqrt ( 3 )/ 3
**
use x in place of theta
0 < x &#8804; 2&#960;
a. sin x=-&#8730;2/2
x=5&#960;/4 and 7&#960;/4 (reference angle of &#960;/4 in quadrants III and IV where sin<0)
..
b. sec x=-2&#8730;3/3
x=5&#960;/6 and 7&#960;/6 (reference angle of &#960;/6 in quadrants II and III where sec<0)
