@derekowens is this series of video cover every difficulty of complex numbers? i'm studying it RN for university test next year..

[derekowens]

@LFCPlatina No this is just an introduction to the topic. I cover some more in the Precalculus class, but most of that is not on YouTube.

@derekowens I hate to sound picky and snobbish about this, but im surprised you haven't said anything about the actual name of the operation of the "absolute value". The Modulus.

[derekowens]

@suntzu53 Thanks. Not picky or snobbish, and the comment is appreciated, and that's a good point. It simply didn't come to mind when I was recording. However, re-recording these is on my list of things to do, and I will try to remember to add that.

are you planning on doing something about the trigonometric side of complex numbers? It's too late for me now, my exams tomorrow, but i'm sure it would help alot of other people.

[derekowens]

@killani64 Yes, I cover that in the Precalculus class. Interesting material. I need to re-record those videos before I post them, though.

I found this series of videos, looking for help on complex numbers so I could understand elementary quantum mechanics (Leonard Susskind's Stanford Lectures can be found on youtube). I am confident after watching all 11 videos (including the 2 historical ones, which I thought were great) that I understand what complex numbers are. You are a great teacher.

Oh man! You totally rock! This helped me soooo much! <3

[Heyydogwithththat]

I had know idea what any of this was until watching this video. Thank You.

Thank you... oddly enough the question I have on this tutorial sheet is |3+4i|. My brain was hurting so much to try and figure out why the answer is 5... my brain feels good now :D

Thanks so much man it helps alot

[TwinkiexTacoxGod]

can u show an example of an absolute-value with complex numbers involving a radical???

[MissONTM]

any videos on using complex numbers with the quadratic formula?

[Ericman2043]

i did some thing wrong lol,i squared 3i instead of 3 :(
