WebBut BA is 1x1 and acts on Bx which is 1x1, so if BA isn't 0, the eigenvalue of BA is k. But shouldn't 0 also be an eigenvalue. If ABx=0x, BA (Bx)= B (ABx)=B (0)=0. Edit: I think I found my mistake. If ABx=0 then yes, x is an eigenvector of AB but because A is nx1, the only vector it can act on to bring to 0 is a 1x1 vector which has to be 0. Web(c) If AB and BA are defined then AB and BA are square. (d) If AB = B then A = I. linear algebra True or false (give a good reason)? (a) If the columns of a matrix are dependent, so are the rows.
