The image shows a unit circle centered at the origin with labeled points $A$, $B$, and $C$. The coordinates of these points correspond to specific values on the circle.

The coordinates of each point are as follows:

• Point $A$: Located in the first quadrant, on the circle at approximately $(1, 0)$, but slightly below the x-axis. This point could represent $\left(\cos(0), \sin(0)\right) = (1, 0)$.
• Point $B$: Located in the third quadrant, near $(-1, 0)$, likely representing $\left(\cos(\pi), \sin(\pi)\right) = (-1, 0)$.
• Point $C$: Located in the fourth quadrant, possibly near $(0, -1)$, representing $\left(\cos\left(\frac{3\pi}{2}\right), \sin\left(\frac{3\pi}{2}\right)\right) = (0, -1)$.

It appears to be a trigonometry problem asking to select the correct points on the unit circle, likely corresponding to specific angle measures.

Would you like a detailed explanation of the trigonometric values at these points or help solving a related problem?
