SOLUTION: Answer must be in radians. Thanks!
2sin^2x + 3sinx-2 =0
I factored it and was left with (2sinx-1) (sinx+2)
I set it =0 and now have sin(y) =1/2.

Question 1045452: Answer must be in radians. Thanks!
2sin^2x + 3sinx-2 =0
I factored it and was left with (2sinx-1) (sinx+2)
I set it =0 and now have sin(y) =1/2.
My homework has the answers on the back so we need to show our work.
But the answers are 7pi/6 ,11pi/6 which have -1/2 as their y cord
What did I do wrong since I have a positive 1/2? Answer by ikleyn(52817) (Show Source):

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2sin^2x + 3sinx-2 =0 ---> Factor ! --->
(2sinx-1)*(sinx+2) = 0
The equation deploys in two independent equations:
1. 2sin(x) - 1 = 0 ---> 2sin(x) = 1 ---> sin(x) = ---> x = and/or x = .
2. sinx+2 = 0 ---> sin(x) = -2. ---> this equation has no solutions.
Answer. The solutions are x = and/or x = .
Do not start your writing saying "Answer must be in radians."
