    i guess you are supposed to figure you are in quadrant 1, otherwise you cannot know for certain what cosine or tangent is

    sine is the second coordinate look at the unit circle on the last page of the cheat sheet find the point where the second coordinate is \(\frac{1}{2}\) the cosine is the first coordinate of that point

    ok I found it so its, √3/2? which must mean that tan is 1/√3?

    although if you have answer choices, the tangent might be called \(\frac{\sqrt3}{3}\)

    same thing, just with the denominator rationalized
