Show your work where appropriate in order to receive credit. Use appropriate symbols to indicate what you are doing. The number of points a problem is worth is found in the square brackets, [ ].

You may use your book, notes, and other resources I have provided. You must not work with another person on this exam. If I have evidence that you worked or copied someone else's work you may lose all points for that problem or potentially you will receive a zero on the exam; that goes for the other person as well. To avoid this potential problem, do not take this exam with someone else; do not talk about the problems in this exam with someone else. Instead, you can use problems from the homework as a conduit if needed. Do not compare answers with someone else.
