December 1, 2010 The time for this test is 2 hours. This is a closed book test, but you are allowed two formula sheets. The formula sheets cannot contain any examples. You should write your name on the formula sheets and turn them in with your exam. You may use a calculator on this test. You must show your work to receive credit for a problem. Note that some problems are worth more points than other problems, and the problems are not necessarily sorted in order of difficulty or point value. You must sign the honor statement at the end of the test in order to receive any credit.
