16-15 Specifying the Complex Number
Imaginary Unit
In mathematics, the imaginary unit i allows the real number system R to be extended to the
complex number system C.
In electrical engineering and related fields, the imaginary unit is often written as j to avoid
confusion with a changing current, traditionally denoted by i.
Your ClassPad lets you specify either "i" or "j" for the imaginary unit.
