Linear equation, span, vectors, linear systems of equations

  1. show that S and T have the same span in R^3 by showing that the vectors in S are in the span of T and vise versa.

    S= {(1,0,0), (0,1,0)}
    T= {(1,2,0), (2,1,0)}

    im a little confused on how to start off on this problem.. help?!

    Well, basically you just do what they suggested. For example, how would you show (1,2,0) is in the span of (1,0,0) and (0,1,0)?
  4. thats what im confused about.. how would i start it off..?
