Unit 3 Problems

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%.
Use graph paper or quadrille (crosshatch) paper when you are asked to plot vectors, lines, etc.
Do extra credit problems entirely on your own.
