Hello, it's been a while since i did linear algebra. i need some help. I have this matrix: 1 1 0 0 1 0 0 0 0. I know the eigenvalues are 1,1,0; and that the eigenvectors will be: (1,0,0), (0,0,0) and (0,0,1). But I cannot do the jordan decomposition on the matrix i.e. write it in the form...

looking over, i finally get it: i need to change the exponent...Taylor series...(someone should have hinted at that lol) thnx i appreciate all your help guys

ps...i really don't get it, and I'm not looking for easy handouts...it just so happens that for some reason, i can't do this particular problem, and would like to know how to, prior my test... i deleted the post because i was changing it to respond to a new post, i think this is my first time...
