Question: User: $\tan30$
1. The problem is to find the value of $\tan 30^\circ$.
2. Recall the definition of tangent in a right triangle: $\tan \theta = \frac{\text{opposite}}{\text{adjacent}}$.
3. For special angles like $30^\circ$, we use known exact values from the unit circle or special triangles.
4. The value of $\tan 30^\circ$ is $\frac{1}{\sqrt{3}}$.
5. To rationalize the denominator, multiply numerator and denominator by $\sqrt{3}$:
$$\tan 30^\circ = \frac{1}{\sqrt{3}} = \frac{1}{\sqrt{3}} \times \frac{\sqrt{3}}{\sqrt{3}} = \frac{\sqrt{3}}{3}$$
6. Therefore, the exact value of $\tan 30^\circ$ is $\frac{\sqrt{3}}{3}$.
Final answer: $\boxed{\frac{\sqrt{3}}{3}}$
