WitrynaSidenote: It is possible to take square roots of complex numbers. To see why, consider the geometric interpretation. A complex number at $(r,\theta)$ in polar coordinates will have the square roots $(\sqrt{r}, \theta/2)$ and $(-\sqrt{r}, \theta/2)$. This is because the angles add and the magnitudes multiply during complex multiplication. For ... WitrynaA square root can be negative – for example, when we take the opposite of the principal square root of a positive number.
