Answer 1

To determine the coordinates of a point on the unit circle at an angle of $ \frac{11\pi}{6} $, we use the unit circle properties.

The coordinates can be found using the cosine and sine of the angle:

$ x = \cos \left( \frac{11\pi}{6} \right) $

$ y = \sin \left( \frac{11\pi}{6} \right) $

Since $ \frac{11\pi}{6} $ is in the fourth quadrant, we know:

$ \cos \left( \frac{11\pi}{6} \right) = \cos \left( \frac{\pi}{6} \right) = \frac{\sqrt{3}}{2} $

$ \sin \left( \frac{11\pi}{6} \right) = -\sin \left( \frac{\pi}{6} \right) = -\frac{1}{2} $

So the coordinates are:

$ \left( \frac{\sqrt{3}}{2}, -\frac{1}{2} \right) $

To determine the coordinates of a point on the unit circle at an angle of $ frac{11pi}{6} $, we use the following trigonometric identities:

$ x = cos left( frac{11pi}{6}
ight) $

$ y = sin left( frac{11pi}{6}
ight) $

Given that $ frac{11pi}{6} $ is in the fourth quadrant:

$ cos left( frac{11pi}{6}
ight) = frac{sqrt{3}}{2} $

$ sin left( frac{11pi}{6}
ight) = -frac{1}{2} $

The coordinates are:

$ left( frac{sqrt{3}}{2}, -frac{1}{2}
ight) $

To find the coordinates at $ frac{11pi}{6} $:

$ x = cos left( frac{11pi}{6}
ight) = frac{sqrt{3}}{2} $

$ y = sin left( frac{11pi}{6}
ight) = -frac{1}{2} $

The coordinates are:

$ left( frac{sqrt{3}}{2}, -frac{1}{2}
ight) $
