Determine the cosine and sine values at $ frac{pi}{4} $ on the unit circle
Answer 1
Lily Perez
To find the cosine and sine values at $ \frac{\pi}{4} $ on the unit circle:
$ \cos \left( \frac{\pi}{4} \right) = \frac{\sqrt{2}}{2} $ $ \sin \left( \frac{\pi}{4} \right) = \frac{\sqrt{2}}{2} $
The values are:
$ \cos \left( \frac{\pi}{4} \right) = \frac{\sqrt{2}}{2} $ $ \sin \left( \frac{\pi}{4} \right) = \frac{\sqrt{2}}{2} $

To determine the cosine and sine values at $ frac{pi}{4} $ on the unit circle:
$ cos left( frac{pi}{4}
ight) = frac{sqrt{2}}{2} $ $ sin left( frac{pi}{4}
ight) = frac{sqrt{2}}{2} $
Answer 3
Henry Green
The cosine and sine values at $ frac{pi}{4} $ on the unit circle are:
$ cos left( frac{pi}{4}
ight) = frac{sqrt{2}}{2} $ $ sin left( frac{pi}{4}
ight) = frac{sqrt{2}}{2} $
