    You are told that R lies on the positive y axis and so why would 2 not be right?

    Edit, it is right.

    If you have a question, make a new post, don't edit the OP... c'mon.

    Anyways, you should know that \pi \mapsto 180^{\circ} \Rightarrow \frac{\pi}{6} \mapsto \frac{180}{6}^{\circ}

    oops, so to convert from degrees to radians it's divide by 180 then multiply by pi?

    oky i though it's be easier for ppl to see

    The y-axis is when x=0. \sin (0 + \pi/6) = \sin(\pi/6) = \frac{1}{2}
