Linear independence and orthogonaliy

  1. Jan 20, 2009 #1
    Please refresh my memory; if a finite set S is L.I., then does this imply the existence of a set T of the same size (i.e. |T| = |S|) so that the elements T are pairwise orthogonal?

    If it's in an inner product space, you can use Gram-Schmidt to find T.

    yes. i believe any method you use (eigenspace, nullspace, etc) to find a set that spans T will be mutually orthogonal. i'd probably guess that the basis spanning T would be orthogonal to the basis spanning A as well.
