Question 601312
Find exact values for all the solutions to the equation for {{{sin theta=negative sqrt( 2 )/2}}} for the values of theta between negative two pi and positive two pi. 
**
sinx=-&#8730;2/2 (-2&#960; < x < 2&#960;)
From-2&#960; to 0
x=-&#960;/4 and -3&#960;/4 (in quadrants III and IV where sin<0)
..
From 0 to 2&#960;
5&#960;/4 and 7&#960;/4 (also in quadrants III and IV where sin<0)
