Now if u did the same........and inside the unit circle.........made like i said before........another concentric circle.........sharing the same center.......but a diff radius.............it would have 4 diff. radius's...........why.?...........B/c it would have parts in all directions..........

To the West..........- 1/2.........to the East...........1/2......to the South........- 1/2 i.....to the north 1/2 i....odd.......

Complex Plane

Real and Imaginary make Complex

A Complex Number is a combination of a Real Number and an Imaginary Number:

A Real Number is the type of number we use every day.
Examples: 12.38, ½, 0, −2000

When we square a Real Number we get a positive (or zero) result:

2² = 2 × 2 = 4
1² = 1 × 1 = 1
0² = 0 × 0 = 0

What can we square to get −1?

?² = −1

Squaring −1 does not work because multiplying negatives gives a positive: (−1) × (−1) = +1, and no other Real Number works either.

So it seems that mathematics is incomplete ... 

... but we can fill the gap by imagining there is a number that, when multiplied by itself, gives −1
(call it i for imaginary):

i² = −1
