SOLUTION: So i need to solve the trigonomic equation sin(2x) + sin(x) = 0. So i use sin(2x)'s identity and get 2sin(x)cos(x) + sin(x) = 0. I have no idea where to go from there.

You can put this solution on YOUR website! Factor out sin(x) and then use the Zero Product Property. Then you will have two fairly easy Trig equations to solve.
