Solution
Solution Steps
Step 1: Find \(\sin \frac{\pi}{3}\)
The sine of \(\frac{\pi}{3}\) is a well-known value from the unit circle. It corresponds to \(\frac{\sqrt{3}}{2}\). Therefore, the correct choice is:
\[
\sin \frac{\pi}{3} = \frac{\sqrt{3}}{2}
\]
Step 2: Find \(\cos \frac{\pi}{3}\)
The cosine of \(\frac{\pi}{3}\) is also a standard value from the unit circle. It corresponds to \(\frac{1}{2}\). Therefore, the correct choice is:
\[
\cos \frac{\pi}{3} = \frac{1}{2}
\]
Step 3: Find \(\tan \frac{\pi}{3}\)
The tangent of \(\frac{\pi}{3}\) is calculated as the ratio of sine to cosine:
\[
\tan \frac{\pi}{3} = \frac{\sin \frac{\pi}{3}}{\cos \frac{\pi}{3}} = \frac{\frac{\sqrt{3}}{2}}{\frac{1}{2}} = \sqrt{3}
\]
Therefore, the correct choice is:
\[
\tan \frac{\pi}{3} = \sqrt{3}
\]
