Linear Algebra 1.2.1 Row Reduction and Echelon Forms

[@zuko803]

I really want to cry because I had rough and difficulties in math at high school, I barely understand math, it was lucky i graduated with D, I want to fix my life for better career, I want to study math for my career, you are my saviour in math, thank you, God bless you maam

[@Kidpunk98]

You're videos are amazing! You are such an inedible teacher, I guarantee you this channel will blow up if you keep it up. please keep up! You are saving me in discrete math, and linear algebra as well!

[@SawFinMath]

Thanks!

[@shadmankhan1969]

She's inedible?

[@SpeaksYourWord]

Spoiler alert: it didn't

[@Bulptheblob]

Your*

I just ate her I disagree with this

[@mr2seis388]

wow, thank you very much for your videos! I was honestly on the verge of quitting. God bless you. Thank you from the bottom of my heart.

[@sghosh7049]

I like your definition: some books don’t distinguish between the row echelon form and the reduced version, but you did ! Very clear, and with nice examples! 😊

[@jesseabiire8980]

thank you very much, your last 3 videos saved me from trailing this course

[@Ky-tk8eh]

Clear and concise videos! I love that the videos are organized and are to the point. For your new videos, I think it would be great if you could add "Chapters" so that it would be easier to locate specific topics within the video.

[@SawFinMath]

Thanks for the tip! Usually I am pressed for time, so I don't do that. But will make an effort to in the future.

[@Siddharth-Prabhu]

I passing my engineering exam tomorrow because this! Thank you!

[@sketchydwarf]

Just wanted to say Thanks! Taking an online summer course and jus like previous rodp courses there are no lecture videos, just an etext mymathlab, and professor says use youtube... well here I am. Thanks for the lectures! Very clear and to the point!

[@elisabethdabrowski1098]

great teacher, there is no substitute to see a problem evolve on the board thanks for including your lectures on youtube

[@jong.4864]

Thank you so much for doing these videos!!

[@clarapaz3236]

Really great video (and also every other video in the playlists)! Super helpful, thanks!

[@SawFinMath]

Thanks!

[@naomeefreedman9194]

Thank you so much for this, you are an amazing teacher! Lord bless.

[@SawFinMath]

Thank you so much!

Replacement should always be the go to for operations before scaling and interchange. For example with the first operation having been scaling R2 by 1/2 you could have instead done -R3 + R2 -> R2. This would have the extra benefit of not working with fractions later. So it should be replacement>scaling>interchange(and really only when leading non-zero needs to be put into better form)

At 3:38, would the purple matrix you created on the bottom right prove existence because of the bottom row, which is essentially 0*x1 + 0*x2 + 0*x3 + 0*x4 = 0, and since 0=0 is true, would prove existence? Edit: I just watched your "Linear Algebra 1.2.2 Solution Sets and Free Variables" and it clarifies that yes, the solution does exist since 0=0! For those who are also wondering as well, if it was 5=0, for example, it would fail existence.

[@sofiavinas7144]

thank you so much, I can't understand my professor so these videos are a god send

[@SawFinMath]

Glad you like them!

[@human0thingss]

Thank you Kimberly, you saved me from my professor

[@chessketeer]

Thank you very much for this very clear lesson! You are a great teacher.

[@sovietwizard1620]

Thank you so much for your videos, I just wanted to try learning linear algebra randomly even though its not in our curriculum for highschool this year. I'm so thankful because one question involving the rotation matrix appeared (where we were given x prime and y prime and had to find the angle given the (x,y) original), and I was not only able to solve it easily, but also the only one in class who managed to do this. So thank you very much!! I didn't realize linear algebra was this useful

[@codingwithelhacen990]

Very helpful lectures... Thank you

[@SawFinMath]

Thanks!

[@anunaysharma2718]

Thank you so much for these lectures :D

[@ticketpirates]

thank you....still following

[@SawFinMath]

Thanks! Working on Calc II now.

[@morongwamolaba]

I love how you are making learning be fun🤣,oh just kidding

[@longolongogoodson1285]

Hello professor Kimberly Zambia is following u

[@cubby091398]

My College Algebra had this type of math in it. However, isn't this more like a Linear Algebra concept?

[@helentravers7409]

Pivot! Did you sneak a Friends joke in there? ❤️

[@v-hypertopic7757]

making them decimals complicated things when i got a 9 as the leading coefficient in my second pivot second row

[@feilongish]

Great stuff. Complete

[@YunessRachidi]

Thank you.

[@Spongebob_Squarepants]

May i use the bathroom please?

[@Bulptheblob]

no, sir... please stop trying to bust open the class's door

[@jewel_throne2950]

Brilliant

[@kevinagee5085]

thanks

[@torstenvwn]

thanks!

[@musfiratalha4656]

best

[@xbz24]

Amazung stuff¡

[@NeoUnfazed]

i don't see why i need to go to college...

[@SawFinMath]

For the degree. Knowledge is power, but knowledge doesn’t pay without the degree.

[@cikechukwujohn]

😄

[@cubby091398]

I want a Bachelor's Degree in Middle School Mathematics with a Minor in Mathematics. I am going take this course instead of differential equations. This seems more easier to understand.

[@fernandoalejo]

THANKS

[@seanobrien347]

practice prior to execution... yikes.

[@zramdeen]

lmao she's not entitled to do anything. its a free online course... yikes.

[@zappist751]

ur a big yikes lol she did it perfectly smh
