Some preliminary remarks.

If coming in late or leaving early, please sit near the back and use the rear entrance/exit, quietly.

If you want to play with your laptop, read email, look at pornography or whatever, stay in the back rows so you don't distract
the people behind you.  (Or maybe stay home.)

It would be courteous to  me if people in the front rows refrained from texting etc. on their cellphones and faked attention.
Look puzzled and nod occasionally. This can more or less be done on autopilot.

For a low-tech way to do slope fields, google "slope fields calculator marek" or use the disc with the book.

Review: Chapters

Look at the HW problems as well as review sheets for Midterm1 and 2, and also Midterm1&2 solutions.



Midterm exams  will  be as indicated below (approximately). For exact dates and a review of what will
be on the exam, come to class.





Goals.  Our goal is to learn the basic ideas and techniques of qualitative, numeric and analytic approaches to differential equations. In particular, we will use geometry to interpret, visualize and investigate short/long term behavior of actual physical systems modelled via solutions of differential equations.

Expectations.
    1.  We expect you to come to class, on time. You are responsible for everything that happens in class whether or not you attend. If you must miss a class, you must notify me in advance in order to be allowed to make up the work (phone, email, note in mailbox, or verbal communication).
    2.  We expect you to work outside of class. Homework is work to be done at home - we will  spend  tiime at the beginning of the class going over homework exercises. You are welcome and encouraged to work together on homework and to get help from other sources (friends, instructor, Math Center)but it's a good idea to write up solutions yourself.
    3.
    4.  
No make-up exams will be given unless you notify your teacher in advance with a valid excuse.

                                              A note on the exercises

The above outline contains a list of proposed exercises for each section of the text we discuss. Many of them are odd-numbered, so the answer appears in the back of the book. Do not look at the answer until you have given the problem your ``best shot.'' In many cases, the book offers an adjacent, parallel exercise, which you might also try if you have any difficulty with the assignment.

 


                                                      
                                                               Academic Integrity

("Beginning with the fall semester 2000, syllabi should include a warning about academic misconduct,
particularly cheating and plagiarism."
 See http://vm.uconn.edu/~dosa8/code2.html .)

"A fundamental tenet of all educational institutions is academic honesty;
academic work depends upon respect for and acknowledgement of the research
and ideas of others. Misrepresenting someone else's work as one's own is a
serious offense in any academic setting and it will not be condoned."

"Academic misconduct includes, but is not limited to, providing or receiving
assistance in a manner not authorized by the instructor in the creation of
work to be submitted for academic evaluation (e.g. papers, projects, and
examinations); any attempt to influence improperly (e.g. bribery, threats)
any member of the faculty, staff, or administration of the University in
any matter pertaining to academics or research; presenting, as one's own,
the ideas or words of another for academic evaluation; doing unauthorized
academic work for which another person will receive credit or be evaluated;
and presenting the same or substantially the same papers or projects in two
or more courses without the explicit permission of the instructors involved."

"A student who knowingly assists another student in committing an act of
academic misconduct shall be equally accountable for the violation, and
shall be subject to the sanctions and other remedies described in The
Student Code."
