Quiz 5 will be in the usual classroom on Friday, March 11. It will cover mainly sections 3.4 and 3.5, plus a repeat problem from an earlier quiz. Understand how to find the phase angle \alpha from the expression A cos(\omega x) + B sin(\omega x). Be able to write trial solutions for the method of undetermined coefficients.

Remember that no mechanical assistance or electronic device of any kind is to be used, other than a super-basic non-programmable non-graphing calculator (although that is not really necessary). As usual, you will receive a quiz and some blank paper. Please write your solutions on the blank paper, write your name on the quiz itself and on your solutions, and turn both in. Request additional blank paper if you need it during the quiz.
