    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!

    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.

    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.

    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

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

    • @SawFinMath
      @SawFinMath  หลายเดือนก่อน +1

      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?

    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?

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