..
The problem is to find the reference angle and the quadrant it is in.
Starting from zero and going counter-clockwise, make one revolution which covers 360�.
To cover 480� you need to go another 120�. This puts you in quadrant II where the sin function is positive. The reference angle is the angle the terminal side makes with the x-axis, which would be 60� in this case. Therfore, Sin 480�= Sin 60� in quadrant II=√3/2
