$\tan (30 °)$

Step 1

To convert degrees to radians, multiply by $\frac{π}{180 °}$ , since a full circle is $360 °$ or $2 π$ radians.

$\tan (30 °) \cdot \frac{π}{180 °}$ radians

Step 2

The exact value of $\tan (30)$ is $\frac{\sqrt{3}}{3}$ .

$\frac{\sqrt{3}}{3} \cdot \frac{π}{180}$ radians

Step 3

Multiply $\frac{\sqrt{3}}{3} \cdot \frac{π}{180}$ .
