Answer 1

To find the value of the function \( y = \sin \theta \) when \( \theta = \frac{\pi}{3} \), we can reference the sine values of common angles.

The sine of \( \frac{\pi}{3} \) (or 60 degrees) is known to be:

\[
\sin\left(\frac{\pi}{3}\right) = \frac{\sqrt{3}}{2}
\]

Thus, the response that corresponds to this is:

**Start Fraction Start Root 3 End Root over 2 End Fraction**

So, the value of \( y = \sin\left(\frac{\pi}{3}\right) \) is \( \frac{\sqrt{3}}{2} \).
