  • I wish I had the will power to watch these videos before exam time so I wouldn`t have to cram like this

  • Amazing job, trying to get ready for linear algebra exam tomorrow.

  • Thanks so much, this is EXACTLY what i needed! :D

  • absolutely amazing!!! u are a genius, thanks sooooo much

  • Thanks guy you just saved me from my mid-term!

  • Doesn't this mean that the dimension of A is equal to the number of collumns minus the number of rows of A. Since the reduced row echelon form will allways contain a number of pivots equal to the number of rows?

  • Comment removed

  • Hi there, I would like to know if I did exactly like you did in the video, except I put in row echelon form instead of a row reduced echelon form. Would I still be able to get the right answer?

  • Thank you sr!

  • A thank you would not be enough . . . I dont know wat to say

    God Bless You

  • Thanks this was very helpful :)

  • is the solution space the same as the nullspace?

  • in this case, Ax=0, your solving for zero->so the

    null space is the solution set. But if your solving

    Ax-b, then solution set is different

  • thx mate..u saved me from failing maths.....lolz

  • You make it so clear. Thank you

  • Null space = Kernel?

  • yup

  • Dude, awesome.
