Product of pseudo-inverses Suppose A and D are right-invertible
matrices and the prod-
uct AD exists. We have seen that if B is a right inverse of A
and E is a right inverse of D, then EB
is a right inverse of AD. Now suppose B is the pseudo-inverse of
A and E is the pseudo-inverse of
D. Is EB the pseudo-inverse of AD? Prove that this is always
true or give an example for which it
is false....

Suppose A and B are matrices with matrix product AB. If bi, b2, ..., br are the columns of B, then Ab, Ab2, ..., Ab, are the columns of AB 1. Suppose A is an nxnmatrix such that A -SDS where D diag(di,d2,... dn) is a diagonal matrix, and S is an invertible matrix. Prove that the columns of S are eigenvectors of A with corresponding eigenvalues being the diagonal entries of D Before proving this, work through the following...

Limits and Continuity 4 Chapter Remark: In the statement of Theorem 4.4.12 we assumed that f was tone and continuous on the interval I. The fact that f is either stric tric. strictly decreasing on / implies that f is one-to-one on t one-to-one and continuous on an interval 1, then as a consequence of the value theorem the function f is strictly monotone on I (Exercise 15). This false if either f is...

Product of pseudo-inverses Suppose A and D are right-invertible
matrices and the prod-
uct AD exists. We have seen that if B is a right inverse of A
and E is a right inverse of D, then EB
is a right inverse of AD. Now suppose B is the pseudo-inverse of
A and E is the pseudo-inverse of
D. Is EB the pseudo-inverse of AD? Prove that this is always
true or give an example for which it
is false....
