Linear Algebra: nxn Determinant

[globotron27]

great for nontraditional students who didn't do this stuff in high school. I need these things "dumbed down" (I mean that in the most respectful way). Thanks for the help!

[JayLaher]

This is so much better than how my instructor or my book explains things. It's exactly the same stuff, but more in a way that can be understood precisely.

Hey, anyone knows what he is using to write like this?

[DerMetzgermeisterF]

@iMantiz I guess he is using a wacom cintiq.

Otherwise mouse skill: level asian :p

Thanks for this video!

the cramer method is fastest way of getting a 3x3

[itechkid]

Multiplying by 0 is the shiznit.

Sal, you rock as usual.

thank you so much, this is brilliant, it made such an impact!

[MrGrimR34p3r]

“Hopefully you found that useful” as I stare at a huge thing of writing. Well I’m glad it’s useful indeed…

[pimpinlittleman]

thanks sal ur a life saver it helped me so much on my act!!!!!!!!!!!!!!

[narical]

sal u should post videos for computer science major !!!!!!!!

[apoltix]

This is explained a million times better than my college text book and whatever resources I could find on the internet. Thank you very much!

[epgmw]

Thanks a lot, very helpfull indeed. Keep up the good work

Cool, I was making a Class Library in C# for matrices and needed a method for determining the determinant. It was much easier than I originally thought it would be to implement (because of recursion). Sal, you should do some Computer Science videos. I'm tired of everyone asking me to tutor them.

[akshayzz1]

@Kaish3k I second that.

[fetish1989]

sal why dont you teach me the math behind electromagnetics. could sure use your help there haha

[MrCalhoun]

Lol I tried solving this via transforming it into an triangular matrix and then just taking the determinant by calculating the product of the primary diagonal elements. Turned out that I copied a number wrong and I kept wondering if I have done anything wrong since my determinant always became 0. :D

I also once used Laplace to calculate the determinants in some homework. Turned out I've forgotten about basic determinant rules and so I calculated the easiest stuff with the most difficult way.

God bless you dude I really mean it ! =)

[LagartoNET303030]

Awesome !!! =D

[trousien]

it is far too impractical to find determinants over 3x3 it takes foreverrrrrrrrr

[roycool76]

I have to say, i missed the first class when we started the determinants! my teacher was no help, but wow this video just put everything at its place! THX YOU SO MUCH

[11SwingAndAMiss]

WOW. You should write the textbook... this is so much less confusing... I regret buying the textbook....

[Aghoriii]

thank you Sal you are amazing

[aduitdfeklfhl]

this voice is different..... its not the same man.....hmm

[C0rnM0]

It's Sal!

[yupm1]

everything is good, but working with rows it's best way, try to make zeros , and than when u make the matric 3x3 or smaller u just calculate it so easy..

[dannyboy12357]

i appreciate your vids : )

[Cyanide1One]

Sal you is the bestttt brooo

[farshadguitar]

I came back to say thanks sallllll !

I had my test today and everything i was writing was exactly your words lol

[Phene1986]

ur the man
