Find a basis for the orthogonal complement of W
Homework Equations
None
The Attempt at a Solution
I can do this question except for the fact when i get the matrix in form
[2,1,-2/0
4,0,1/0]
i get to this bit but saying the complement is equal to (col(A))=null(A^T)
i can't perform reduced matrix stuff when there is not an odd number at the front i just can't do it can someone start of the next step for me? if so i can do the rest of the question
it is a resit i have tomorrow and we were told today that this question is in it, so it is worth a lot for me to know it by then
