Remember: The text believes that you can think. There will not be an example in the book exactly like every homework problem.

All assignments are from Calculus by Hughes-Hallet, Gleason et. al., (John Wiley & Sons, New York, Fourth Edition, 2005).

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 pages.
Do not copy collaborative solutions; write up solutions in your own words.
Turn in homework on time. Late homework will not be graded.
Write-up rules include the following.
- Assert equalities. Do not just list expressions; tell what they are equal to.
- Keep equations balanced. Do not change just one side of an equation, thus making the assertion of equality false.
These are corollaries of the general rule: Say the right thing, and say it right.
Do extra credit problems entirely on your own. Submit them separately from regular homework.
