Please see below.
Work Step by Step
By using the identity $e^{i \theta }= \cos \theta + i \sin \theta$, we have$$e^{\frac{\pi i}{6}}=\cos \frac{\pi }{6} + i \sin \frac{\pi }{6}=\frac{\sqrt{3}}{2}+\frac{1}{2}i.$$Now, we plot the complex number $z=\frac{\sqrt{3}}{2}+ \frac{1}{2}i$ the same way we plot $(\frac{\sqrt{3}}{2}, \frac{1}{2})$ in the rectangular coordinate system.
