Find the value of $sin$ and $cos$ for specific angles using the unit circle
Answer 1
Isabella Walker
Using the unit circle, find the values of $\sin$ and $\cos$ for the angle $\frac{\pi}{4}$.
For $\theta = \frac{\pi}{4}$:
$\sin\left(\frac{\pi}{4}\right) = \frac{\sqrt{2}}{2}$
$\cos\left(\frac{\pi}{4}\right) = \frac{\sqrt{2}}{2}$
Answer 2
Joseph Robinson
Using the unit circle, find the values of $sin$ and $cos$ for the angle $frac{pi}{3}$.
For $ heta = frac{pi}{3}$:
$sinleft(frac{pi}{3}
ight) = frac{sqrt{3}}{2}$
$cosleft(frac{pi}{3}
ight) = frac{1}{2}$
Answer 3
Sophia Williams
Using the unit circle, find the values of $sin$ and $cos$ for the angle $frac{pi}{6}$.
For $ heta = frac{pi}{6}$:
$sinleft(frac{pi}{6}
ight) = frac{1}{2}$
$cosleft(frac{pi}{6}
ight) = frac{sqrt{3}}{2}$
