http://im54.gulfup.com/SJgJXh.png Till now compared with other subjects that I studied by my self, linear algebra is really the toughest one
Anyway, here I found a plane using characteristic eq. which really surprised me since det(M)=1, M is the matrix I've posted.
##-2x+y+z=0## , how is that? a rotation around plane! in which dimension that's possible!, as the book did I took a vector satisfy the plane that's ##(1,1,1)##, then I found ##\theta = π##
Everything is correct according to book solution. But I'm not convinced yet! a plane has a lot of vectors in many directions nevertheless we derived the axis of rotation from plane eq.?! that's really weird.
Thanks a lot guys.
