Discussion Overview

The discussion centers on how to graph the inequality |z| > 3 on the complex plane. Participants seek a detailed explanation of the graphical representation, including the implications of the inequality in terms of geometric shapes.

Discussion Character

  • Exploratory, Conceptual clarification, Homework-related

Main Points Raised

  • One participant asks for guidance on how to graph |z| > 3, expressing uncertainty about the visual representation.
  • Another participant explains that |z| represents the distance from the origin, indicating that the graph involves a circle with a radius greater than 3.
  • A different participant reiterates their confusion about the graphical representation and suggests that the graph could be illustrated by drawing the circle |z| = 3 and shading the area outside of it, although they acknowledge this method is not perfect.

Areas of Agreement / Disagreement

Participants express varying levels of understanding regarding the graphical representation, with no consensus on the best method to illustrate the inequality.

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,
$$|\pi\rangle$$
 
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.
