Homework Help: Zwiebach page 258

  1. Nov 9, 2007 #1
    1. The problem statement, all variables and given/known data

    On this page Zwiebach says that an arbitrary matrix can be decomposed into a traceless-symmetric part, an antisymmetric part, and the identity matrix times a constant. Isn't that only true when the original matrix has all off its diagonal elements equal, though?

    EDIT: never mind; I figured it out-- the symmetric matrix matrix is traceless which does not mean that each diagonal element is 0, sorry
    2. Relevant equations

    3. The attempt at a solution
