Identify the sine and cosine values for the angle $ frac{pi}{4} $ on the unit circle.

Answer 1

Abigail Nelson

Michael Moore

To find the sine and cosine values for the angle $ \frac{\pi}{4} $ on the unit circle, we use the definitions of sine and cosine:

$ \sin\left(\frac{\pi}{4}\right) = \frac{\sqrt{2}}{2} $

$ \cos\left(\frac{\pi}{4}\right) = \frac{\sqrt{2}}{2} $

Answer 2

Alex Thompson

Emily Hall

For the angle $ frac{pi}{4} $ on the unit circle, the sine and cosine values are:

$ sinleft(frac{pi}{4}
ight) = frac{sqrt{2}}{2} $

$ cosleft(frac{pi}{4}
ight) = frac{sqrt{2}}{2} $

Answer 3

Amelia Mitchell

Joseph Robinson

The sine and cosine values for $ frac{pi}{4} $ are:

$ sinleft(frac{pi}{4}
ight) = frac{sqrt{2}}{2} $

$ cosleft(frac{pi}{4}
ight) = frac{sqrt{2}}{2} $
