Not sure if this is "beyond" Calculus but the prereq for the class was Calc II so I thought i'd post here. 1. The problem statement, all variables and given/known data Could a set of n vectors in Rm span all of Rm? 2. Relevant equations None 3. The attempt at a solution Hmm really stuck at this one. I think that it should be able to span since the only thing that matters is if you have a pivot point in each column? So even if you have say 3 vectors in R4 it could still span it, since you can have still have a pivot point in each of the column if the vectors allow it? Thanks for the help.
