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.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

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...

Re: imaginary numbers
Those are not imaginary numbers. They are complex!

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

Re: imaginary numbers
Hi cooljackiec;
|5-12i|+|3-4i| = 13 + 5 = 18
