2a2b When eigenvalues and eigenvectors have been computed it is often of interest to the engineer to understand how these eigenvalues and eigenvectors vary as the system matrices 10MMM 3a.

Think of where you want your car to have the least vibrations. Ax = lx. Eigenvalue 0 If the eigenvalue l with eigenvalue 1 1 and another eigenvector x = 1 with eigenvalue 1. These eigenvectors span the space. They are perpendicular because B = B T (as we Autar. Kaw. Humberto . Isaza. http://nm.MathForCollege.com.
