    I just want to say thank you for your in-depth discrete math playlist. Saved my life for my discrete math exam.. This channel deserves more recognition.

    I got a 60 on my first exam, watched and took notes on all of these videos before the midterm (instead of going to lectures im afraid), and got a 90 on the midterm. Thanks!

    I don't mind the usage of etc. I love the lectures and they have helped me tremendously as supplementary material to my LA class. Thank you so much!!!

    First you saved me in discrete math and now you're saving me in linear algebra, thank you !

    I think this video gave me the biggest "ah-ha" moment that I've ever had learning math. Not a single part of this concept made any sense to me until it suddenly all clicked into place. I have an exam tomorrow so this video saved my grade. Thank you!

    How does this video only have 41 likes out of 2900 views? What else do you people want?!
    Thank you for this course!!

    Thank you for producing this series. Due to the amount of material my professor must cover in one semester, she moves too fast for me to adequately comprehend and internalize the information. I used your videos to review for my midterm and earned 100%! (After scoring a 68% on a previous quiz). I truly appreciate your videos because they are well-produced and clear. I also can watch them as often as needed until I understand the concepts.

    Whenever there is a math course final , I come here for quality revision and insights.
    Thanks a lot for your effort providing these great lectures.

  • @anakinkylo.thepomenerianan9084

    may God bless you for your effort & time making these videos. Most videos on linear algebra are too basic => these are perfect

    Yall so lucky to have legit math and science youtube videos. I was stuck with indian tutorials and they weren't much help😥

    p(t) and q(t) don't necessarily have the same degree, and typically we should use different letters for the degree exponent, such as n and m.

    How could I have made it in linear Algebra without this Channel? . Merci beaucoup

  • @superRdelarosa

    Is this material appropriate for supplementing “Linear Algebra and it’s Applications “, 5th Edition textbook. Thank you.

    • @SawFinMath
      @SawFinMath  Před rokem

      Yes. This book follows the 5th edition of Lay's text.

    Hi, where can I get more example questions and answers where I can practice?

    • @SawFinMath
      @SawFinMath  Před rokem

      I suggest picking up a copy of the textbook, David Lay's Linear Algebra. Lots of practice questions.

  • @mikarpman

    I'm a bit confused about your answering the question of whether the space of polynomial functions is a subspace of all real valued functions. At about the 8-minute mark of the video you you check for the requirement of multiplication being closed. Previously I thought you would said that this was scalar multiplication. But in this example, it seems that you are checking to see if the polynomials are closed under a different form of multiplication rather than scalar multiplication. Have I misinterpreted something here or did you slip up?

    • @pianodan1608
      @pianodan1608 Před rokem

      Yeah I realized that as well.

    • @cooking60210
      @cooking60210 Před rokem

      What she said isn't right. It should be closure under scalar multiplication.

    • @cooking60210

      She slipped up.

    i dont understand the last example, what does it mean by the zero vector not belonging to H?

    • @SawFinMath
      @SawFinMath  Před dnem

      The zero vector [0 0 0] must belong to a vector space. Since the middle term of our. Vector is 4, it is impossible for the zero vector to be H (since 4 can never equal zero). Does that make sense?

  • @darkrose3509
    @darkrose3509 Před 3 měsíci

    at 17:53 i still dont understand how 0 is not an element in H just because there is a four. Can't you times H by 0 to make it a zero vector? like 0 x 4 = 0

  • @thesharkmusic8852

    What is this text book ??I want it

  • @user-mk8gi3hu5w
    @user-mk8gi3hu5w Před 9 měsíci

    Why 0 belongs to the H in the 2nd last question but not the last question????
    If anyone got that please explain it.

    • @lareina9316
      @lareina9316 Před 7 měsíci

      She explains in the video, because of the 4 constant, you can never have the 0 vector, which is a requirement for a subspace

    • @youtubeexpert2441
      @youtubeexpert2441 Před 5 měsíci

      your explanation sounds like gibberish to me. please ELI5@@lareina9316

    • @hasanal-dhubaibi1507
      @hasanal-dhubaibi1507 Před 20 dny

      ​@@lareina9316 ok, but then how can I show that 0 does not belong in H in the exam? I can't just write that 0 does not belong in H without doing anything. I hope you can tell us if you know how to do that.
