![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
