    Hey mate, I just wanted to let you know that I checked out your website and what you're doing is fantastic. I'm taking a machine learning class and we're still in the early stages (fitting lines to data and such). I'm ready for the calc and stats but totally forgot about the equation of a plane (used to construct to construct hypotheses via multivariate linear regression) so here I am. I'm gonna pass along your website to some of my college friends because only good can come of it. Oh, and greetings from the US!

    I spent 2hours watching a long length video but I was still confused until I finally discovered your video. every question in my head have their answer now.

    I have to drop this comment, you have made me have a deep understanding of what appears vague in my textbook. Thanks a lot
    I wish you more success on your platforms

    Thank you for this video, only question is : if a different point is chosen for P on the plane, D will be different and the equation will be different, depending on what point we choose, wouldn't it? Or points that are on the plane will always give the same D value? Thank you.

      Change your perspective; the 90-degree angle is not 'flat' on the plane.
      It wasn't mentioned but d is the shortest distance (perpendicular distance) to the plane from the origin. This is a fixed property of the plane and is independent of the choice of point P on the plane. Also, ON is normal to the plane so any point that lies on the plane P will be at right angles to N.

    THANK YOU SO MUCH!! This was extremely helpful.

    But if d is a constant, wont it vary depending on the r value, if r is different, and since unit normal vector will remain the same, shouldnt d vary

      Bit late but I think d is when r is when r is normal, so although r varies d is the specific case where the vector to the plane is perpendicular and therefore the shortest distance to the plane.

    How is Big D exactly different from smaller d

    • @ExamSolutions_Maths
      @ExamSolutions_Maths  5 років тому +1

      d represents the distance from the origin to the plane. D = constant x d
