For an invertible matrix A, prove that A and A- have the same eigenvectors. How are the eigenvalues of A related to the eigenvalues of A Letting x be an eigenvector of A gives Ax = ix for a corresponding eigenvalue A. Using matrix operations and the properties of inverse matrices gives which of the following? AX = Ax Ax = Ax Ax/A = Ax/A Ax- Ax AXA- = AXA1 Ax ix A-Ax = Aix Ix - JA-x x = 2A-x Ax = ix A/(Ax) - A/(Ax) OA/A)x- (A/A)x O(A/A)x - xA- Ix - (A/A)x Ax - 1x 1x A"x = 1x This shows that --Select- v is an eigenvector of A with eigenvalue -Select-
