am a computer science student at cairo university, our course in the linear algebra isn't good at all. Most of my collages watch ur videos to be able to now what the linear algebra is, Thank u so much for this awesome playlist, an extra note, We used to call u "Tant", It's an Egyption word that used to be told to women to show respect 😂🥰♥♥♥♥. again, Thank u so much, and I hope u continue ur amazing work In the beautiful channel.
I searched for the meaning of the word Tant, and indeed it is used as a form of respect for old womans, but also means Aunt, and that is incredible, because here in brazil, when we are young we do not refer to our teachers as Mr or Mrs, we call female teachers as Aunt and male teachers as Uncle.
I'm taking Linear in the fall and these videos have been a tremendous help. I tried following the MIT Linear Algebra videos and just could not follow all of them. Much love and appreciation for your efforts Professor.
Been using this for the last 5 lessons and have been loving them!! Thank you so much for these videos! They're so short and sweet, and they teach me more than my prof does in 2 hour lectures. Would love to see more videos on the lessons that werent seen in this playlist like 1.9 and 1.10 but thank you so much!
10:08 at this point in the video you just take row1 and subtracted by row3 and replaced at row3 I can't really see how you managed to do it with just a row replacement operation, I can only do it by doing two operations - Replacement on Row3 targeting Row1 multiplying with -1 then Scaling Row3 with -1
your videos are fantastic, but I have to say, the amount of non-skippable ads you put on your educational videos is appalling, it sometimes makes it difficult to grasp the concept when your explanation is interrupted by 30 seconds of ads
since x_3 is a free variable (and we're left with an all-zero row at the bottom), there's no matrix row operations you could use to get rid of either of the two values without messing up the pivots. for that reason, the answer is defined with respect to x_3
clutching up linear algebra the night before my finals, godsend

I'm so glad I'm able to help! And I will take the compliment!!

@@NikesDarkslayerYoo, almost the same in Kazakhstan. I guess it's popular in lots of cultures

Absolute facts, my professor does 3 hour lectures and yet are explained in the most complicated way ever
What textbook is being used?
just fantastic as simple as possible thank's a lot your videos were really helpful
Amazing lecture! Thank you
Thank You Ma'am🌹
So, at 12:18 , why did you not multiply row 1 by 8 so you can get rid of the 2 in the second row
That would be a bad choice because if you did that, Row 2 Column 1 would turn to an 8.
thanks you so much, my teacher did not teach this
Hi, at 0:41 you wrote Ax = 0. I think it is supposed to be A(vector X) = vector 0.
complete stuff
So non-pivot columns indicate free variables ?
Correct
Is there only one way to get the matrix in reduced row echelon form?
There is only one reduced row echelon form. You can get to it a different way, but only one solution
@@SawFinMath Thank you
@@SawFinMath @ 14:24 Why didn't you continue to reduce the 2 in row 2 column 3?That could be made into a zero right?
I love you

- Replacement on Row3 targeting Row1 multiplying with -1 then Scaling Row3 with -1
13:09 why is it -2? are we subtracting?
@15:31, where do the x1 and x2 go?
your videos are fantastic, but I have to say, the amount of non-skippable ads you put on your educational videos is appalling, it sometimes makes it difficult to grasp the concept when your explanation is interrupted by 30 seconds of ads
Who cares bro let her get her bag, this info is gold
she has done so much for us she deserve it 🙂
Why did you leave two numbers in column 3 at 13:00?
since x_3 is a free variable (and we're left with an all-zero row at the bottom), there's no matrix row operations you could use to get rid of either of the two values without messing up the pivots. for that reason, the answer is defined with respect to x_3
