Topic: Imaginary Numbers


In Mathematics, Imaginary Numbers are Complex Numbers whose sqaure is negative.

Square Root of Negative One

The Sqaure Root of -1 is usually denoted as: i. As in:

i = √-1

However, with some groups, i and I represent Electrical Current. In these groups, j is used to denote the square root of -1. As in:

j = √-1

This is often called operator j.

This is not to be confused with the use of j with Quaternions.

Example Imaginary Numbers

Some examples of complex numbers include:

2i + 3
i - π
π - i
π - i√5
