* These are merely some suggested problems.
You should work as many problems as necessary to master the ideas.
Unless otherwise indicated, the problems are from our text,
Linear Algebra: Ideas and Applications, by Richard Penney.
Homework rules
- Acknowledge your sources (people and texts).
- In nontrivial problems, show how you get your answers.
- Turn in neat, well-written solutions, not messy first drafts.
Trim "fringes." Staple.
- Do not copy collaborative solutions; write up solutions in your own words.
- Turn in homework on time. Each class day late reduces the possible points
by 25%.
- Do extra credit problems entirely on your own.
Proof Portfolio (Perfect Proofs)
- Problem 1.1 #9
- Problem 1.2 #22
- Problem 2.2 #10
- Problem 3.3 #18
Proofs
- Proofs should be written in complete sentences. Mathematical
expressions should be embedded in a grammatically sensible way. Look
at your math texts to see how this is done.
- Every step in a proof is or can be justified by a reason.
Valid reasons include assumptions, definitions, and previously
established results. The extent to which reasons are omitted and
proofs abbreviated depends on the audience.
