comment If two sets (including A) are mutually exclusive, then A is the union of the sets.
Thanks! I was looking at it in the wrong "direction"!

I think you mean "since t is not in the subspace spanned by u, v and w."

Thanks, David! That's what I needed! Weird how it's so obvious after someone told you where to look...

comment Different results for row reduction in Matlab
@J.M. and Agusti, I think I might have narrowed it down to a rounding error, causing the top and bottom row to be slightly different (but not shown due to lack of decimals shown in Matlab). As you are both more experienced here than me, do you think I should answer my own post or delete it? Thank you!
