Convert the point on the unit circle given in Cartesian coordinates $(sqrt{3}/2, 1/2)$ to its corresponding angle in degrees and radians, and verify the solution by converting the angle back to Cartesian coordinates.
Answer 1
We are given the point $(\sqrt{3}/2, 1/2)$ on the unit circle. To find the corresponding angle, we use the following trigonometric relationships:
$x = \cos(\theta)$
$y = \sin(\theta)$
Thus, we have:
$\cos(\theta) = \sqrt{3}/2$
$\sin(\theta) = 1/2$
For the angle $\theta$ that satisfies these equations, we recognize that these are standard values. The angle $\theta$ is $30^{\circ}$ or $\pi/6$ radians.
To verify, we will convert $30^{\circ}$ back to Cartesian coordinates:
$\cos(30^{\circ}) = \sqrt{3}/2, \sin(30^{\circ}) = 1/2$
Thus, the point $(\cos(30^{\circ}), \sin(30^{\circ})) = (\sqrt{3}/2, 1/2)$ matches the given point. Therefore, $\theta = 30^{\circ}$ or $\pi/6$ radians.
Answer 2
Given the point $(sqrt{3}/2, 1/2)$ on the unit circle, we find the corresponding angle using the relationships:
$cos( heta) = sqrt{3}/2$
$sin( heta) = 1/2$
Since $cos( heta)$ and $sin( heta)$ match the values at $ heta = pi/6$, the angle is $30^{circ}$ or $pi/6$ radians.
We verify by converting $pi/6$ back to Cartesian coordinates:
$cos(pi/6) = sqrt{3}/2, sin(pi/6) = 1/2$
The point $(cos(pi/6), sin(pi/6)) = (sqrt{3}/2, 1/2)$ matches. Therefore, $ heta = 30^{circ}$ or $pi/6$ radians.
Answer 3
Given $(sqrt{3}/2, 1/2)$, we find:
$cos( heta) = sqrt{3}/2$
$sin( heta) = 1/2$
These are at $ heta = pi/6$. Checking Cartesian coordinates gives $(sqrt{3}/2, 1/2)$. Hence, $ heta = 30^{circ}$ or $pi/6$ radians.
