Solution

For this case we have the following number given:


-3+\sqrt[]{3}i

We can see that x = -3 and y = - sqrt(3)

The angle is given by:


\arctan (\frac{-\sqrt[]{3}}{3})=-30=-(\pi)/(6)

The radius would be:


r=\sqrt[]{(3)^2+(-\sqrt[]{3})^2}=\sqrt[]{12}

And the polar form would be given by:


z=\sqrt[]{12}(\cos (-(\pi)/(6))+i\sin (-(\pi)/(6)))\text{ }
