    Unclear what is wanted. \(3\sin(\theta) = \sin(\theta) - 1\) Is that it? Can you solve... 3x = x-1?

    Okay, what is the solution to the little x-problem?

    So, why wouldn't the solution to the original problem be \(\sin(\theta) = -1/2\)?

    Right. And which is consistent with \(\sin(\theta) = -1/2\)?

    No good. sine is positive in Quadrant I and sin(pi/2) = +1 If you have a negative sine, you should hang out in Quadrants III and IV.
