    This playlist is great! Im currently taking a linear algebra course in university and these videos actually help me to better understand the material! Thanks for the content 👍🏼

    Could you do a video on the Dirac Delta Function plz?

    Very nice video and proof. Your notation is really hard to read, but aside from that, excellent stuff!

    Do more derivation videos.
    I'm only just out of highschool and I have no idea where these random integrals come from. The only videos I can understand/follow along with are the derivation ones.

    Please make one for three dimensions or maybe if possible a generalization.

      everything it just the same only the matrix become 3x3 or u can find it from wiki type rotation matrix on google

    this is actually a linear transformation in linear algebra u can also flip reflect skew and many many others transformation

    So the reflection matrix of y-axis is ...(-1,0,0,1)-oh yeah that's hot! Btw,congrats on 40k subs!

    I have a question, is there a particular matrix that will allow you to reflect a vector across this plane (x+y+z=1)

  • @asbjrnandersen4765

    Do you do these derivations on the go or do you have a paper you follow from

    • @smrtfasizmu6161
      @smrtfasizmu6161 4 роки тому +1

      I guess he makes derivations first on paper then he derives it on the board but I could be wrong, he is a graduated mathematician, he can probably do it on the fly and make the video go so smoothly without any hint that he is doing it for the first time

      yeap, and its equal to "im" on "Lim" for Limits. Learning maths

    Why u cant derive the result with simply rotational matrix multiplication of (2gamma)by a vector v?
