Determine the cosine value at specific points on the unit circle.

$\text{Consider the point where the angle is } 60^\circ \text{ on the unit circle.}$

$\text{The cosine of } 60^\circ \text{ is given by } \cos(60^\circ) = \frac{1}{2}. $

$\text{Therefore, the cosine value at } 60^\circ \text{ on the unit circle is } \frac{1}{2}. $

$ ext{Consider the point where the angle is } frac{pi}{3} ext{ radians on the unit circle.}$

$cosleft(frac{pi}{3}
ight) = frac{1}{2}. $

$ ext{Therefore, the cosine value at } frac{pi}{3} ext{ on the unit circle is } frac{1}{2}. $

$cos(60^circ) = frac{1}{2}.$
