# Math Help - Really easy question about how to find several angles.

1. ## Really easy question about how to find several angles.

Hello, i think i am missing a key part of trig. I am sure it is easy, but i can not seem to find material on it. for 2sin(theta)^2=sin(theta) the answer is 0, Pi, pi/6. 5pi/6. I know how to find Pi/6, but I am not sure where to get the other answers.

Thank you for any help provided.

2. $2\sin^2\theta =\sin\theta$

$2\sin^2\theta-\sin\theta=0$

$\sin\theta(2\sin\theta -1)=0$

Now

$\sin\theta=0$ and $2\sin\theta -1=0$

Can you finish it?

3. yeah, I see what i forgot to do. Thank you for showing me.
