[NganaJHone]

I am very happy to see the vidoe from you, hopefully the others also are happy for You Determinant Formulas and Cofactors.

[Ondelendo]

Steady I Really Like This Video Determinant Formulas and Cofactors.

[bebeheuy]

Good, I like that you share this video Determinant Formulas and Cofactors., I wish success always

[willamricard]

Nice Video Determinant Formulas and Cofactors That You Share , So Very Nice Thanks You

[imegatrone]

I Really Like The Video Determinant Formulas and Cofactors.From Your

[bundawartini]

Your Video Determinant Formulas and Cofactors Is Very Useful Sharing

[anakmudajaman]

after i watched this video Determinant Formulas and Cofactors, my insight is very open because the video is very good to give information

[matrixkernel]

The last example was really neat.

[TheMacyp]

I wish I was studying there...

At least he makes sense and explains things clearly and well.

Here at the IST in Portugal, I have to watch video lectures on youtube so I can actually understand something!

[scrappyOoOcoco]

thank you. Pf Strang. U have so many 30000 students with a positive slope

[akhil089]

thanks professor gilbert

[houari2009]

24:40 LMAO, the professor is very funny, "keep walking away"

[hypnoticpoisons]

the professor is not only brilliant but humorous!

[hypnoticpoisons]

14:45: such as beautiful picture

[hypnoticpoisons]

he's gonna kill all of them, what an assassin:D

[reid300]

ha that is not as bad as at my school when the grads are having their iron ring ceremony they all run through the 1st year classes hammered and spraying silly string and whatever else they find yelling and causing a general ruckus.

[stiffz]

Grim the Reaper forgot how to do his determinants.

[serkanvai]

haha :) "as long as it is not periodic" 25:00 very mathematical comment

[thedeathofbirth]

U R GR*!!!!!

[adrienspawn]

cool

[HermanTHW]

Sudoku!!!

[TRUTHOFISLAM]

On our faculty they didn't tell us anything about 3-diagonal. GREAT video and thx for the lecture.

[Milliaamy]

Great professor changed his shirt

[frkngrpnr]

hahahaha, 18:49

[h4ck3rm1k3]

This guy is great!

[rubelcool]

what r those guys come often in the middle of lectures. I saw those guys (in other costumes of course) in many other different lectures of MIT.

[ru0107]

haha 24:40 a great moment in linear algebra... don't know if he was making a pun when he said "were EXECUTING a determinant formula"

[thou9009]

Do you know what "to execute" means? It's not a monosemic word. The context within which it is used here is entirely appropriate:)

[ru0107]

Do you know what a pun is? At 24:40 what you could call an executioner walks through the room and then he says "we were talking about executing a determinant."

[thou9009]

Good save, buddy.

[Milliaamy]

It is definitely a pun. So hilarious.

[MartinTheNext]

this lecture is awesome

it finally made me undersrand the leibniz formula! thanks a lot

[tehinfidel]

Last segment is interesting: |A_n| = |A_n-1| - |A_n-2| looked awfully fibonacci-like. It turns out that the determinants of the symmetric tridiagonal matrices with i in the non-diagonal entries exactly follows the Fibonacci sequence.

Mind blown yet again.

[albperjet]

great observation

[Mathematics215]

Wow, that is a very cool fact.

Those crazy complex tridiagonals, what will they do next.

[austkast]

24:35....very odd.

[berkeley73]

from today in HD - what a difference!
