### imaginary numbers

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

I see you have graph paper.

### Re: imaginary numbers

hi scientia

Nice solution.

So where are the imaginary numbers?

Perhaps you have to imagine them.

Hi bobbym

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

Those are not imaginary numbers. They are complex!

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
