.
2sin^2 theta plus 3sin theta = -1
Solve for the given domain:
0greater than or equal to theta greater than or equal to 2pi
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

 = ,

 = .

Factor left side:

(2*sin(theta) + 1)*(sin(theta) + 1) = 0,   --->

 =   or   = ,  --->

 =   or   = -1,  --->

Solutions:

1.     =   or   = 

or

2.     = .
