Awesome Answer from Linear Algebra April 16, 2009
Today in Linear Algebra, we were learning about vector spaces and bases of them. In short, the basis of a vector space V is a subset S of V such that each element of S is linearly independent from each other and S makes up all of V. We were given the the set S = {(1,0), (1,1), (1,2)} as a subset of R2 and asked to determine the span of S and whether or not S is a basis of R2.
The kid next to me answer for the first question with, span(S) = {(3,3)}. I have no idea why he thought that this was a good answer. First of all, (3,3) isn’t even in S. Secondly, all he did was sum up the elements. Seriously, wtf?
