Matrices, cauchy-schwarz and tringla inqualities?

  1. Dec 1, 2009 #1
    Right I've been given 2 2x2 matrices
    A =
    |1 1|
    |0 1|

    B =
    |1 0|
    |1 1|

    And I have to find the triangle

    and cauchy schwarz

    inequalities with the innerproduct defined as <A,B>=trace(ABt) where Bt is B transpose.

    Now I've got no idea how to do it (I really hate matrices) so can someone push me in the right direction? thanks in advance!
