... There is one free variable: x1 , so we set x1 = t. The first row of A − 3I gives x2 = 0. Thus, a vector x is in the eigenspace of 3 if ...

... >To intensify this oddity, consider the fact that all inertial frames are equivalent. That is, from the traveler's point of view he is the one who is sitting still, while I zip past him at 0.6 c. So he will think that it is MY clock that is running slowly. This lends itself over to what seem to be p ...

A Brief on Linear Algebra
... do not, think of the set R as a vector space over the field R. Our purpose in pointing this out is really the observation that for this very simple vector space, there is a single vector, namely the vector 1 in terms of which every vector in R can be represented as an appropriate multiple. For examp ...
