What is the cosine of $30^{circ}$ on the unit circle?
Answer 1
Amelia Mitchell
To find the cosine of $30^{\circ}$ on the unit circle, we need to recall the coordinates of the point on the unit circle corresponding to $30^{\circ}$. The coordinates are $(\frac{\sqrt{3}}{2}, \frac{1}{2})$.
The cosine of an angle is given by the x-coordinate of the corresponding point on the unit circle.
Therefore, the cosine of $30^{\circ}$ is $\frac{\sqrt{3}}{2}$.
Answer 2
John Anderson
First, we locate $30^{circ}$ on the unit circle. The point on the unit circle at $30^{circ}$ has coordinates $(frac{sqrt{3}}{2}, frac{1}{2})$.
Since cosine is the x-coordinate, we find:
$ cos{30^{circ}} = frac{sqrt{3}}{2} $

Olivia Lee
The coordinates of the point at $30^{circ}$ are $(frac{sqrt{3}}{2}, frac{1}{2})$.
Thus, $cos{30^{circ}} = frac{sqrt{3}}{2}$.
