Linear equation, span, vectors, linear systems of equations

  1. Sep 10, 2011 #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)?
