Find the value of $ cosleft( frac{pi}{3}
ight) $
Answer 1
Maria Rodriguez
The value of $ \cos\left( \frac{\pi}{3} \right) $ can be found using the unit circle. The angle $ \frac{\pi}{3} $ corresponds to 60 degrees. On the unit circle, the coordinates for the angle 60 degrees are:
$ \left( \cos\left( \frac{\pi}{3} \right), \sin\left( \frac{\pi}{3} \right) \right) = \left( \frac{1}{2}, \frac{\sqrt{3}}{2} \right) $
Therefore, the value of $ \cos\left( \frac{\pi}{3} \right) $ is:
$ \frac{1}{2} $
Answer 2
Lucas Brown
To find $ cosleft( frac{pi}{3}
ight) $, note that it corresponds to 60 degrees on the unit circle. The coordinates at 60 degrees are:
$ left( frac{1}{2}, frac{sqrt{3}}{2}
ight) $
Thus, $ cosleft( frac{pi}{3}
ight) = frac{1}{2} $
