    \[\sin 120=\sin (180-60)=\sin 60=\sqrt {3}\]

    just remember that on the unit circle, sin is your y-coordinate cos is your x-coordinate.

    Still on the top-half of the unit circle, so sin is positive there...

    oh i see, so since sin is the y axis, it would be sqrrt3/2

    correct... sin is the y-coordinate, not the y axis...
