I have no idea where to post this.

How to graph |z| > 3 on the complex plane? A detailed explanation of how the graph shall look like would be very nice :D

Thanks!

Hello,
|z| means length of z from origin, so the length of the circle is greater Then 3
Regards,
\(\displaystyle |\pi\rangle\)

I understand that, but I have no idea how the graph should look like. I don't know how to draw it to illustrate that the radius is greater than 3.

I think the simplest way to graph this is to draw the circle |z| = 3, then shade the outside of the circle. It's not perfect, but it gets the idea across.
