Using the table above, determine the coordinates on the unit circle corresponding to a 45° angle.
| Angle (°) | Radians | Coordinates |
|---|---|---|
| 45 | $$\frac{\pi}{4}$$ | $$\left(\frac{\sqrt{2}}{2},\frac{\sqrt{2}}{2}\right)$$ |
| 30 | $$\frac{\pi}{6}$$ | $$\left(\frac{\sqrt{3}}{2},\frac{1}{2}\right)$$ |
| 60 | $$\frac{\pi}{3}$$ | $$\left(\frac{1}{2},\frac{\sqrt{3}}{2}\right)$$ |
A
$$\left(\frac{\sqrt{2}}{2},-\frac{\sqrt{2}}{2}\right)$$
B
$$\left(\frac{1}{2},\frac{\sqrt{3}}{2}\right)$$
C
$$\left(\frac{\sqrt{2}}{2},\frac{\sqrt{2}}{2}\right)$$
D
$$\left(\frac{\sqrt{3}}{2},\frac{1}{2}\right)$$
