1) Determine the two angles
sin(2θ)=0.9179.
2)Determine the solution sets
12cos^2θ=3
I have no idea of what is happening when the professor explains how they got the angles or soln sets, they automatically know what quadrant it is in and what angle it should be, and what the next angle(s), sets are. I cant imagine it. I don't know how they see that on the unit circle.
