    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! 😊

    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.

      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.

    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

    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)

    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

    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.

      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.
