Hey folks - I left my linear book at home for the summer and am having trouble finding this on the Google, so I'm hoping you'll be good for an easy question :) I have a set of vectors that I think spans a vector space, but I've forgotten how to test it. I can make a set of 5 simultaneous equations (it's a 5-dimensional space) but that seems a bit much. How do I do this again? I'd also appreciate a reminder about how to test for linear independence, though it seems with this particular set of vectors that part is pretty trivial. Thanks!!
