Webspace vector de ned by the quatenion. Then the eigenvalues of Aare p ijvj, both with algebraic multiplicity 2. The characteristic polynomial is p A( ) = ( 2 2p + jzj)2. 17.11. Every normal 2 2 matrix is either symmetric or a rotation-dilation matrix. Proof: just write down AA T= A A. This gives a system of quadratic equations for four variables ... Webx(1),x(2) extend to a fundamental set of solutions, with other n−m =n−2 solutions corresponding to other eigenvalues of A. It is interesting to note, by multiplying (2) by (A−rI), we have (A−rI)2η =0. Subsequently, we ONLY consider problems with eigenvalues with multiplicity two, with only one linearly independent eigenvector.
Web(1) The numbers are the algebraic multiplicities of the eigenvalues , respectively. (2) The geometric multiplicity of the eigenvalue is the dimension of the null space . Example 1.

To find the eigenvalues you have to find a characteristic polynomial P which you then have to set equal to zero. So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment. great lakes school closure form
