Linear Algebra 1.2.1 Row Reduction and Echelon Forms

[Kidpunk]

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!

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! 😊

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

[jesseabiire]

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

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.

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.

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!

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

[naomeefreedman]

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

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

Thank you so much for doing these videos!!

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

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

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

Thank you so much for these lectures :D

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.

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

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