Line 152:
::[-1,1,0] isn't a unit vector; it has norm \sqrt{2}.
::In linear algebra, vectors are typically concieved as going from the origin to some other point in space. This leads to a common notational ambiguity; does a n-tuple represent the coordinates of a point in space, or a vector from the origin to the point? It could be either; the context helps if you really need to know. But often you don't, which only encourages the laziness. [[User:Endomorphic|Endomorphic]] 02:43, 5 December 2006 (UTC)
:::My mistake, I don't know where my mind was – but an excellent example of laziness :-) – [[User:AdrianLozano|Adrian Lozano]] 23:37, 5 December 2006 (UTC)
