trig help

[shinobi9119]

can someone help me with a trig problem.
I need the find the exact solutino(s) for this equation with the restrictions
0≤y≥2π
2sin^2 x + 3sinx +1 =0
all my hw is this but i figure if i cant get one i can get the rest
^2 means squared so sin squared. It wont llet me use superscripts.
thanks

10 years I've been done with high school and not once have I had to use trigonometry.
Sorry I can't help - it's all gone now!!

1. graph it on ur calculator, then hit solve for zeros (TI89)
2. did you try any trig identities. I know sin^2 is something
