Please note the following guidelines:
  1. * When a problem calls for graphical or numerical approaches, you are to use Mathematica and any of the available Linear Algebra Toolkit on your course's web site. By using mathematica, you get to strengthen or practise using a software that you are already familiar with from Calculus.
  2. &dagger Due dates will be announced in class as we go.
  3. All work must be shown on every problem that you turned in; you need to show the mathematical steps from the beginning to the end. If you would like to earn partial credits from the TA, you need to explain how you arrive at the answer - explain verbally, if you have to.
  4. When a problem asks you to VERIFY a few properties, then all you have to do is to show that the properties are true for that particular or specific example.
  5. When a problem asks you to PROVE or SHOW some statement is true for say, some type of matrices, then you need to argue that the statement is true for ALL matrices of that type, and NOT just show the statement is true for ONE example of matrix of that type.

    Appendix C in your text gives a short introduction to the concepts of mathematical logic and proofs.
