Determine the cosine of an angle corresponding to the point $ left( frac{1}{2}, frac{sqrt{3}}{2}
ight) $ on the unit circle.
Answer 1
Matthew Carter
To determine the cosine of the angle corresponding to the point $ \left( \frac{1}{2}, \frac{\sqrt{3}}{2} \right) $ on the unit circle, we must recognize the coordinates $(x, y)$ represent $(\cos(\theta), \sin(\theta))$.
In this case, the point is:
$( \cos(\theta), \sin(\theta) ) = \left( \frac{1}{2}, \frac{\sqrt{3}}{2} \right)$
Thus, the cosine of the angle is:
$ \cos(\theta) = \frac{1}{2} $

Abigail Nelson
To find the cosine of the angle at the point $ left( frac{1}{2}, frac{sqrt{3}}{2}
ight) $ on the unit circle, we know that:
$( cos( heta), sin( heta) ) = left( frac{1}{2}, frac{sqrt{3}}{2}
ight)$
Therefore, the cosine of the angle is:
$ cos( heta) = frac{1}{2} $
