Find the cosine of the angle at the unit circle

Home Find the cosine of the angle at the unit circle for the angle $ heta = frac{pi}{3} $ Answer 1 Henry Green To find the cosine of $theta = frac{pi}{3}$ on the unit circle, we look at the x-coordinate of the point where the terminal side of the angle intersects the...
