### imaginary numbers

How many pairs of integers (b,c) satisfy the equation

I see you have graph paper.
You must be plotting something

Hi;

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

### Re: imaginary numbers

hi scientia

Nice solution.

So where are the imaginary numbers?

Perhaps you have to imagine them.

### Re: imaginary numbers

Hi bobbym

Those numbers you posted aren't imaginary either...

Why not? What did I do wrong?

Those are not imaginary numbers. They are complex!

Compute |5-12i|+|3-4i|.

### Re: imaginary numbers

a) Suppose we graph every point z  in the complex plane such that |z| = 4. What shape results?

b) What is the graph of the equation |z-2i| = 3

Hi cooljackiec;

|5-12i|+|3-4i| = 13 + 5 = 18
