4/26: 

Some references on game theory: Evolutionary Game Theory, Jorgen W. Weibull (1997), MIT Press A bit mathematical (requires
knowledge of set theory), but good.
Theoretical Evolutionary Ecology, Michael Bulmer (1997), Sinauer
AssociatesA more ecological spin
(hawkdove, etc) on game theory in the later chapters.
Game Theory: A Nontechnical Introduction, Morton D. Davis (1997) Dover
PublicationsHaven't read it, but perused it
on Amazon. Can't argue with the price, and if I am optimistic
about any book that has nontechnical in its title.

Linear Algebra with Applications, 3rd Edition,
by Otto Bretscher
Prerequisite:
Math 12101220 or Math 12501260, first year calculus. Previous
exposure to vectors (in 2210 or 1260) or in a Physics class is useful
but not essential.
Grading:
Grades will be based on homework, two exams, three quizzes, and
one comprehensive final exam. The tentative dates for each of these are
listed below. I expect you to attend class. Should you miss class, you
are still responsible for the homework and material presented that day.
A missed exam or quiz will simply be awarded zero points. Makeup exams
will only be given in extenuating circumstances, and only if I am
notified before
the exam.
The breakdown for the
coursework will be:
Homework: 35%
Midterm exams: 15% x 2 = 30%
Quizzes: 5% x 3 = 15%
Final: 20%
Letter grades will be
assigned based on the following scale:
93100 = A 9093 = A
8790 = B+ 8387 = B
8083 = B
7780 = C+ 7377 = C
7073 = C
6770 = D+ 6367 = D
6063 = D
< 60 = E
Homework:
Homework will be assigned at each class session.
You can expect to hand in homework during one of the following
two class periods after completing a chapter. You are responsible to
hand in homework
on the days indicated when class begins.
Late homework generally will not be accepted.
Should you plan to be absent on a day homework is due, you are
responsible
to make the necessary arrangements to turn in your work before
your absence. In consideration of those
grading
your work, please be legible and clear. In
addition
to announcements in class, the course webpage will have an uptodate
listing
of homework assignments. At the end of the
semester
I will drop your lowest homework score.
Final:
Useful Information
Dropin Computer Lab: All students enrolled
in a math class have access to the undergraduate computer lab next to
the
Computer Labs: Throughout this
semester you will be assigned projects using the computer software
Maple (and perhaps Matlab). The days those
projects are assigned, we will meet in the computer lab in LCB. These projects will be part of your homework
score. I do not assume you have used this
software before and we will have the appropriate tutorial during the
first visit to the lab.
Calculators: You are encouraged to
use graphing and computers to assist you in your work.
However, technology should be an aid
and not a crux! This class is
foundational for higherlevel mathematics classes, and it is important
that you master each concept as it is presented. If
you cannot sketch why you received a particular answer via a computer,
then you do not understand it well enough. Beware: the use of calculators on quizzes/exams will be
discretionary. On homework, quizzes, and
exams you will be tested on whether you understand the material and the
steps leading up to an answer, rather than just brute computation.
Simply writing down an answer to a complicated problem will result in a
loss of points, even if the answer is correct.
Cell Phones &
Pagers: Noise pollution
during
class is a growing problem and is very disruptive and disrespectful to
both
me and your fellow students. Please be sure to turn your devices to
silent
when in the classroom.
Disclaimer: Policies stated
within
this syllabus are subject to change, following verbal announcement in
class.
Students are responsible for knowing the current version, always to be
found
on the course website.
Welcome to class! I look forward to a productive, engaging, and
fun semester.
