 Text: Calculus Elementary Differential Equations and Boundary Value Problems, 9th edition, by Boyce & DiPrima
ISBN 9780470383346, published by Wiley Covering roughly chapters 14, and portions of 58. 
Course Content and Goals:
Upon
completion of this course, successful students will demonstrate the
ability to:
 Identify the basic categories of ordinary differential equations,
and identify appropriate elementary methods to apply toward their
solution;
 Model a wide variety of natural phenomena with ordinary
differential equations, interpret given models and evaluate them for
appropriateness, and interpret the resulting solutions;
 Accurately carry out a variety of elementary solution methods, with understanding of those methods' limitations;
 Make informed choices among various exact and approximate
solution methods, including elementary methods, Laplace transforms,
numerical and series solutions, and qualitative methods, depending on
the nature of the problem and the type of solution desirable;
Grading:
Course Points
Weekly quizzes at 25 points each,
except on exam weeks, drop 2 lowest: 
200 points (approx)

Five to ten WebWork assignments, mostly integration review

approx 5 points each, 2550 points total

Three onehour exams at 100 points each: 
300 points 
One or two group projects at 75 points: 
75150 points 
Comprehensive Final exam: 
200 points 
Total: 
800900 points (approx)

For each graded piece of work, I will post cutoff scores for grades of
A, B, C, C, and D. At the end of the term, if your point total is
more
than the total of the A cutoffs, your grade will be an A or better,
and
so on. However, see the notes below on grade
adjustments.
Cutoffs
will never be higher than this:
A 
B 
C 
C 
D 
90% 
80% 
70% 
67% 
60% 
... but they are often lower.
 Tentative hour exam dates: [Sept. 25 or Oct 2],[Oct. 23 or 30], [Nov. 20 or 25]
 The final exam is on Saturday, Dec.14, 2013, from 811 am
 For borderline grades, I tend to pay more attention to the final
exam
score.
 At the end of the term, I will consider those students who have
done
unusually
small or unusually large shares of their group's project and adjust
their grades accordingly.
Exam makeup policy: Exam makeups or early hour
exams
are given only for verifiable illness or for universitysanctioned
intercollegiate
activities. For collegiate activities, you must see me before
you
leave to arrange a makeup time. In any case, contact me in advance
except
in emergencies.
Final exam time is Saturday, Dec.14, 2013, from 811 am,
as set by the University; early finals will not be given.
Please
make your travel plans now.
Really. I mean it. If someone else will be making your travel
plans, it would be wise to notify them immediately of your
committments.
The project will be done
by assigned groups. One paper per group is to be submitted, and a
common
grade is given.
Quizzes, Homework, and Participation
Quizzes are 15 to 25 minutes long, with problems that resemble
homework.
We will usually have a quiz in any week without an exam or a project
due. Some weeks may be more crowded.
Homework is assigned daily but will not
be collected;
however, skipping or putting off homework will damage your
grade badly. Don't let this happen to you.
Careful and precise exposition of your work is required on exams. Such writing does
not come automatically, so it will help to practice careful writing on
your homework.
Please come to class prepared to discuss the previous night's
homework.
Accommodations for students with disabilities:Accomodations
required by students with disabilities will be provided upon reasonable
advance notice and verification of requirement/eligibility from the Office of Disability Services(Bishop
Wellness Center). If you forsee needing an accomodation,
it is probably best to inquire at the Office of Disability Services at
the start of the semester. If Disability Services prescribes
extra time for exams, you must remind your instructor of your needs at
least one week before an exam and send an email reminder at least three
days before the exam to ensure appropriate accommodations have been
made.
Policy on inclass distractions and cell phones: It
is important to respect the concentration and attention of each student
in the class. Class time is limited, precious, and the tuition is
quite expensive per minute. Arriving late for class is not acceptable barring genuine emergencies.
Electronic devices not required for the course must be turned off during class time.
Exceptions include calculators, and specialneeds aids such as
lecturerecording devices. If your cell phone rings during
regular class time, you will be required to bring pastries or cookies for the entire
class at the next class meeting. During exams and quizzes, the
penalty is more specific: two points for each ring, or one point per
second of audible sound, whichever is greater. Please help me
hold distractions for your fellow students to an absolute minimum.
Workload and time committment expectations
It is the policy of the College of Liberal Arts taht for every hour of
class time there is an expectation of two to three hours of work
outside of class.
Thus, for our class you should anticipate spending six to nine hours
weekly outside of class engaged in study time, reading and homework
assignments, and group work.
Academic Honesty Expectations
All exams and quizzes are to be taken with books and notes closed
(except
as noted on the exam paper), completely on your own. Anything you can
electronically
store on an ordinary graphing calculator is acceptable unless otherwise
directed, but
written notes are prohibited. Use of laptop and tablet computers, smart
phones, and anything else capable of communication with the world
outside the classroom will not be
allowed during quizzes and exams.
On written group assignments, you may (and should) discuss the
problem,
methods of approach, examples you have found, and even the solution(s),
with anyone. You may use any source you find useful, but you must
acknowledge
your sources in writing in the assignment. Grading is based
primarily
on the amount of work and thought that students have applied to their
sources
and the extent to which they have demonstrated understanding of them.
Plagiarism is the copying or paraphrasing of any work from another
source
without proper written acknowledgement. You should not see (or
hear)
the written report or reportdraft of any student outside your group
until
reports are graded. I will treat any such occurrence as plagiarism. All
group members are responsible for knowing all the sources their group's
members used in making a report. All involved with plagiarized projects
will receive failing project grades.
In keeping with college policy, plagiarism will be reported to the
dean
(see student handbook). Systematic or organized plagiarism on exams or
quizzes will result in course failure. If you are uncertain about some
aspect of the academic honesty policy, it is your responsibility to get
clarification from the instructor.
