Unformatted text preview: should duplicate systems used as examples in Section 2.5 or in class. Express each system in the standard Ax = b form. Use x = A\b to solve each of the systems. Briefly discuss the results a. A system with three unknowns and a unique solution. b. An underdetermined system. c. An overdetermined system. 3. Solve problem 40 on page 108. Paste the plot into the document you submit. Note: The answer given in the back of the book for Chapter 2 Problem 40 is really the answer to Chapter 2 Problem 39. The answer to problem 40 is not given. 4. Solve problem 42 on pages 111-112. 5. Solve problem 47 on page 115. 6. Solve problem 50 on page 115.
