### 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.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

### 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...

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
