3. (10 points) Simultaneous left inverse The two matrices 3 2] and both left-invertible, and have multiple left inverses. Do they have a common left inverse? Explain how to find a 2 × 4 matrix C that satisfies CA-CB-1, or determine that no such matrix exists. (You can use numerical computing to find C.) Hint. Set up a set of linear equations for the entries of C. Remark. There is nothing special about the particular entries of the two matrices...

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....

Product of pseudo-inverses :Suppose A and D are right-invertible matrices and the product 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.

State the 5 reasons why the inverses of the 6 trig functions are chosen in the way they are." For example, why is -pi/2 to pi/2 chosen for the inverse sin function. There are many other sections of the inverse sin graph that could have been chosen, so why this one? Each of these reasons is explained in words. Do not separate and address the 6 trig inverses. You are looking at the whole picture. In fact, one or more...
