Instructions:
•
Verify that your exam contains 8 pages (including this cover sheet).
•
Little space is provided for you to show your work. Show your work on the back of the
exam sheets or on additional scratch sheets. Submit extra sheets showing any work you
would like to be considered for grading purposes.
•
Place only the ﬁnal answer in the box provided.
–
If you provide more than one answer in the box, they will be equally weighted.
–
A correct answer contained in your work, but not written in the answer box is worth
only partial credit.
•
Answer forms:
–
“Numerical answers” means the answer should be a numerical expression, decimal
expression is not necessary. For example “1 +
√
2” is O.K., but “1 + 4” is not (i.e.
you need “5”). Showing your work for numerical answers will allow us to give partial
credit for an incorrect answer.
An incorrect numerical answer with no work is worth
no credit.
–
“Function of
T
and
λ
” means that your answer should be an expression involving
T
and
λ
. All other elements of the expression should be numerical.
–
“AlwaysSometimesNever” answers require no explanation unless speciﬁcally re
quested. If an explanation is requested, a correct answer without explanation is
worth little credit.
•
Cheating will not be tolerated.
The minimum penalty for even casual cheating is a failing
grade of 0 on the exam. All instances of cheating will be handled according to university
rules and will be reported to the Dean of Student Aﬀairs.
No.
