Homework rules

You may work with other students on figuring out how to work homework problems, but you must write up the solutions on your own and in your own words.
Acknowledge your sources (people and texts). This is part of academic honesty.
In nontrivial problems, show how you get your answers.
Turn in neat, well-written solutions, not messy first drafts. Trim "fringes." Staple.
Turn in homework on time. Late homework will not be accepted, but your lowest two homework scores will be dropped.
