    Why o why do we even do this?We don't know what we are doing but we still do it. Has math lost its sense, no humans have

      You are doing it because public educations seeks to prepare any person with a wide array of skills such that they can go into any field with some basis of knowledge. I want to do Aerospace Engineering, therefore calculus based applications are really nice to know. You may want to go into some other non-math related field but I do. That's what the other subjects are for, to peak your interest.

    Your video was amazing. This thing was giving a headache to me in 10th grade and you explained it so well. Thanks a ton.

    could you help me by multipying the matix and then subtracting it by a 2x2 matirx! could you use and example sayin evaluate AB -BA of a 2x2 square matirx

    I think you made a mistake while computing BA matrix element a(21).
    you multiplied R2 of B with R2 of A and placed in a(21) of BA. But luckily answer is same!!! wow 👍 at time 2:17. Do check mam.
