Homework for the weekend

Saturday, October 21, 2017

Be sure you've carefully studied the material up through section 1.4 and that you understood the ideas, the definitions, the theorems and proofs, and the examples. If you have questions, be sure to get them answered.

Review the material on elementary matrices on pages 34 and do exercise 1.5.4. Elementary matrices are part of linear algebra and are pre-requisite material for this course. If you'd like to review your linear algebra more thoroughly, I suggest checking out Sheldon Axler's Linear Algebra Done Right. You'll see a link to a free compactified version.

Also, read the paragraph about the principle of mathematical induction on page 35 and do exercise 1.5.7.
