2. Imaginary unitIn mathematics, the imaginary unit or unit imaginary number allows the real number system R to be extended to the complex number system C, which in turn provides at least one root for every polynomial P(x). The imaginary unit is most commonly denoted by i. The imaginary unit's core property is that i = −1. The term "imaginary" is used because there is no real number having a negative square.
