Summary
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:
i
2i
2i + 3
i  π
π  i
π  i√5
