Hello professor, thanks for the video. But I have one question. Whether could we get a vector basis from the vector which has pivot, in this case, 1st column and 3rd column ?Then we have span([-3, 1, 2]T, [-1, 2, 5]T) which includes Matrix A. Could we have one deduction that any vector of null space is orthogonal to any vector in vector space span( basis vector of Transpose(A) )?Could we say the vector space of space span( basis vector of Transpose(A) ) is orthogonal to null space of A? Thanks in advance!
