The symbol i represents something that, when squared, is equal to negative 1.
Because of this property we see math such as the following:
An imaginary number may be the summation of an imaginary component and a real component:
x = 3i + 4
The above has an imaginary component of 3 and a real component of 4.
We might think of a real number as being an imaginary number with a imaginary component of zero.
x = 0i + 4
There is a progression or pattern as we take exponents of i with increasing power:
- the pattern continues…
