test tomorrow need the instructions to how to do this problem.
Question: A=( 0 2) find a matrix B such that C(A)=N(B)
any kind of help please.
Ok so the column space of is the set of all linear combinations of the columns of .
That is all vectors of the following form:
where are scalars.
We could think about these vectors as points in 3-space with certain restrictions: which leads to:
works I think.
