What values for theta (0<=theta<=2pi) satify the equation?
3 sin theta = sin theta - root3
(1)
With (1)
So
We can look at a unit circle to see what values of θ in the interval [0, 2π] will satisfy .
Here is a pretty clear unit circle:

Exactly! You have something to add in my answer or there are something whitch don't tike you?
Thank you.
