What is the value of $sin(30°)$ and $cos(30°)$ on the unit circle?

Answer 1

Abigail Nelson

Daniel Carter

First, we need to recall the values of sine and cosine for common angles on the unit circle. For $30°$ (or $\frac{\pi}{6}$ radians):

$\sin(30°) = \frac{1}{2}$

$\cos(30°) = \frac{\sqrt{3}}{2}$

Answer 2

Alex Thompson

Emma Johnson

To find the values of sine and cosine for $30°$, we can use the unit circle:

$sin(30°) = frac{1}{2}$

$cos(30°) = frac{sqrt{3}}{2}$

Answer 3

Using the unit circle, we see that:

$sin(30°) = frac{1}{2}$

$cos(30°) = frac{sqrt{3}}{2}$
