## Why are imaginary numbers called Imaginary?

(The name dates back to when they were first introduced, before their existence was really understood. At that point in time, **people were imagining what it would be like to have a number system that contained square roots of negative numbers**, hence the name “imaginary”.

## What is i3 equal to?

Answer and Explanation: The value of i3 is **-i**. We can determine this by multiplying i, or √−1 , by itself three times.

## What is i 2 in a matrix?
