$\cos (\frac{π}{3})$

Step 1

The complement of $\cos (\frac{π}{3})$ is the angle that when added to $\cos (\frac{π}{3})$ forms a right angle ( $\frac{π}{2}$ radians).

$\frac{π}{2} - \cos (\frac{π}{3})$

Step 2

The exact value of $\cos (\frac{π}{3})$ is $\frac{1}{2}$ .

$\frac{π}{2} - \frac{1}{2}$
