Final Exam: the final exam will be comprehensive,
covering all material since the beginning of the course. It will
be similar in spirit to the two class tests, but about twice as long.
You will have questions on the material covered after Test 2, in
particular systems of differential equations, so be sure to
review that material. As on Test 2, you will be given
a copy of the table of Laplace transforms as well as
the table summarizing the
Method of
Undetermined Coefficients.
The standard cheat sheet and calculator policies apply:
Cheat Sheet Policy: You may use a
single lettersize doublesided "cheatsheet" for
the final exam. The cheatsheet must be handwritten and
may contain formulae, facts, definitions and
theorems, however your cheat sheet must not
contain worked examples. Your cheat sheet must be
handed in with your exam.
Calculator Policy: A basic scientific
nonprogrammable, nongraphing calculator is
permitted.
