Complex numbers with the same modulus (absolute value)

Показать описание
Sal shows how to determine which members in a set of complex numbers have the same modulus (or absolute value). He also shows how to visualize all of the complex numbers with a given modulus as a circle on the complex plane, since all points on a circle are the same distance from the origin.

I don't know what this means, and I don't even know anything above statistics, but Khan Academy somehow manages to teach it perfectly. Amazing video Sal!

It would be good if they updated the website to use drawing tools like this when working out answers, there is a lot of questions regarding Cartesian co-ordinates, asking whether something is on a circle, inside or outside, or you are given a lot of data and need to plot it to work something out

Hey I actually got it from the picture and the title of the video before it started. But I guess I should have because I'm a mechanical engineer.

And I got through most of my college math by watching Khan Academy videos.

THANKS SAL!

1:28 I don't think that circle is positioned correctly. It looks a little crooked.

What playlist is this? Is there going to be a complex analysis playlist?
