Find the sine and cosine values at $ t = frac{pi}{4} $ on the unit circle
Answer 1
Ella Lewis
To find the sine and cosine values at $ t = \frac{\pi}{4} $ on the unit circle, we use the following values:
$ \sin\left(\frac{\pi}{4}\right) = \frac{1}{\sqrt{2}} $
$ \cos\left(\frac{\pi}{4}\right) = \frac{1}{\sqrt{2}} $
Thus, the sine and cosine values are:
$ \sin\left(\frac{\pi}{4}\right) = \frac{1}{\sqrt{2}}, \quad \cos\left(\frac{\pi}{4}\right) = \frac{1}{\sqrt{2}} $

Christopher Garcia
To find the sine and cosine values at $ t = frac{pi}{4} $ on the unit circle:
$ sinleft(frac{pi}{4}
ight) = frac{1}{sqrt{2}} $
$ cosleft(frac{pi}{4}
ight) = frac{1}{sqrt{2}} $
Answer 3
Joseph Robinson
At $ t = frac{pi}{4} $ on the unit circle:
$ sinleft(frac{pi}{4}
ight) = frac{1}{sqrt{2}} $
$ cosleft(frac{pi}{4}
ight) = frac{1}{sqrt{2}} $
