Find the cosine of $ frac{pi}{3} $ using the unit circle
Answer 1
Michael Moore
Using the unit circle, the angle $ \frac{\pi}{3} $ corresponds to 60 degrees. On the unit circle, the coordinates of this angle are:
$ \left( \frac{1}{2}, \frac{\sqrt{3}}{2} \right) $
The cosine value is the x-coordinate:
$ \cos \left( \frac{\pi}{3} \right) = \frac{1}{2} $
Answer 2
Mia Harris
Using the unit circle, the angle $ frac{pi}{3} $ corresponds to 60 degrees. The coordinates of this point are:
$ left( frac{1}{2}, frac{sqrt{3}}{2}
ight) $
Thus, the cosine value is:
$ cos left( frac{pi}{3}
ight) = frac{1}{2} $
Answer 3
Maria Rodriguez
Using the unit circle, the angle $ frac{pi}{3} $ corresponds to:
$ cos left( frac{pi}{3}
ight) = frac{1}{2} $
