    Here, I explain the typical calculation scheme for getting dimension and basis for the image/range and nullspace/kernel for a given matrix.
    I hope that this helps students, pupils and others.
    (This explanation fits to lectures for students in their first year of study: Mathematics for physicists, Mathematics for the natural science, Mathematics for engineers and so on)

    The first part of explanation is awesome.
    But I didn't understand the range part well since it includes some theory part.
    I hope in the next video I could understand more about range

    This was helpful, thank you. My professor prefers to not give us simple tips like this for some odd reason.

    Basis of range and kernel? More like "Beautiful description for all!" Thanks for making such high-quality lectures.

    Hello thanks for the video.May I know if we want to obtain Range(A),whether we could use expression Range(A)=Span{[2,4,8]^T,[3,1,7]^T}?

      Of course, you can write the range as a span :)

    Great explanation,i have a question for the range,you just need to take 2 linearly independent vectors doesnt matter which duo in this case,you took 1st and 3rd,but u can take 2nd and 4th for the range T basis , as they are independent too right?I guess yes.

    • @brightsideofmaths
      @brightsideofmaths  3 роки тому +2

      You have to take two that span the whole range. In the end, it does not matter but it is also better to have a system which ones you can choose.
