Please read this syllabus carefully. You will be responsible for all the information given here, and for any modifications to it that may be announced in class.

Text: The textbook for this course is Differential Equations and Boundary Value Problems (2^nd edition), by C. Henry Edwards and David E. Penney.

Instructor: Darryl McCullough, Professor of Mathematics

Class Participation: The first day of class, you may select your regular seat, which should be used for all lectures. If you are unable to see or hear properly or are otherwise dissatisfied with your seat, please consult me about a reassignment.

You are expected to attend all lectures, and are responsible for all information given out during them. As explained under ``Grading System'' later in this syllabus, excessive absences will result in points lost from your class participation grade, while superior attendance will add a few extra points to your total.

This course requires your full effort, so it is expected that you will give your complete attention to the instructor for the full class period. Activities such as eating, sleeping, reading, listening to headsets, conversing with other students, and so on do not constitute class participation. Students engaging in such behavior during the lecture may be counted as absent.

Homework: It is absolutely essential to work a large number of problems on a regular basis. Problem assignments for each topic of the course are given on the Class Schedule and Homework Assignments page. To receive credit, homework must be turned in on time, and in the following format:

1.	Use standard sized blank, ruled, or graph paper. Use a looseleaf (preferably three-ring) binder notebook, so that you can easily insert and remove pages. I recommend that you put only a few problems on each page.
2.	Each problem should be clearly and uniquely identified in the format c.s #n, where ``c'' is the chapter, ``s'' is the section, and ``n'' is the problem number. For example, problem 18 in section 3.2 should be labeled as 3.2 #18. The problems should be in the order in which they appear in the book.
3.	The problem itself should be written out, in abbreviated form if appropriate, followed by your solution. Your homework solutions need not be polished masterpieces of mathematical exposition, but should be legible, and the solutions should clearly indicate the steps used to arrive at the solution. If you can write a clear explanation of what you are doing, you will understand it. If you understand it, you will retain it.

The homework notebooks will be collected on the exam dates, which are February 12, March 14, and April 18. The homework will be checked for completeness, with a few problems graded, and this will constitute 15% of your grade.

Homework is collected and examined solely as a learning device to help you master the ideas and techniques of calculus. As a university level student, it is essential for you to allocate your time so as to learn the most with the least effort. For example, crossing out something you want to remove is much faster than erasing, even though the result might not look as pleasing to the eye. The homework assignments are designed to be the bare minimum that a strong student would need in order to achieve the course objectives; it is your responsibility to work extra problems for the topics that give you difficulty, until you have mastered them.

You may consult with other students about the homework problems, indeed I encourage you to do so. However, you should write up the solutions in your own words. It is a complete waste of time to just copy from a solutions manual or from someone else's work. If you decide to turn in work that is not your own, I cannot stop you, but you will not learn the material adequately and you will pay a heavy price on the exams which constitute 75% of your course grade.

Answers to the odd-numbered problems appear at the end of the textbook. For help, you should come to my office hours, or make an appointment with me to come at another time. Email is the best way to contact me (when my office telephone number is busy, it usually means that I am somewhere else and am connected to my office computer via modem).

Testing: The exams will test understanding of some of the theoretical ideas and additional techniques presented in the lectures. These are part of the course and should be learned along with the basic problem-solving techniques used in the homework problems. Examinations will be given during the regular lecture hour on the following dates, covering the listed sections.

The final examination will be held in the usual lecture room on Wednedsay, May 8, 1:30 to 3:30 p. m. University regulations require that you take it at that time. It will cover all sections listed in the class schedule, with some additional weighting to sections 8.1-8.3, since these sections will not be covered on the three in-class examinations.

All tests must be taken at the scheduled times, except in extraordinary circumstances. Please do not arrange travel plans that prevent you from taking any of the exams at the scheduled time. If you cannot take a test at the scheduled time, you should contact me in advance of the test time. Check the grading of your exams carefully when they are returned; all grading errors should be brought to my attention as soon as possible.

Grading system: There will be 300 points possible as follows:

The class participation grade will be determined as follows. If you have 4 absences or less, you will receive the full 30 points of class participation credit, plus 2 bonus points for each class fewer than 4 missed (thus you can earn up to 8 bonus points for superior class participation). The 5^th through 10^th absences will each subtract 5 points from the 30 points of class participation grade.

Course grades will be determined according to the following scale:

Grades are calculated by computer but errors in recording or entering scores can occur. Please keep your tests and homework so that you can verify the posted totals at the end of the semester, if you think that an error may have occurred.

Withdrawal Policy: Until January 28, there is no record of a grade for dropped courses. From January 29 through March 29, you may withdraw and receive a ``W'' grade, no matter what scores you have so far achieved. After March 29, University regulations specify that you may withdraw only in ``very unusual circumstances,'' and only with the permission of the Dean. Avoidance of a low grade is not sufficient reason to obtain permission to withdraw after March 29.

Grade of Incomplete: The grade of ``I'' is a special-purpose grade given when a specific task needs to be completed to finish the coursework. This is typically a term paper or other special assignment, so rarely makes sense in a mathematics course. An ``I'' cannot be given to avoid receiving a low grade.

Students with Disabilities: If you have a disability that may interfere with the demonstration of your abilities, please contact me as soon as possible to arrange accomodations necessary to ensure your full participation in the course.

Final Grades: Grades will be posted on our course website as soon as they are available. You may pick up your graded final exam from me any time within one year of the end of the course, after one year they will be discarded.

Internet Resources: On the Internet there are numerous websites that contain theory, tutorials, and problems with solutions, for calculus and in some cases more advanced material. The ``Teaching'' page on my website has links to some of these sites, and if you follow the link to the UC Davis Calculus Page, there is a much longer list there

Advice: It is important to think about the subject daily or almost daily (you will learn much more in two hours a day for seven days than in seven hours a day for two days). People learn best in small bits through repeated exposure, so it is much more effective to work the homework problems from one section a few at a time over a period of days, rather than all at once in an extended session. This means you may be working problems from several sections of the book at the same time--- this is fine, since they will reinforce each other. If you approach the homework in this way, you will spend no more total time or effort, and will learn much more. Occasional work sessions with fellow students can be very productive, as long as one avoids the pitfall of becoming dependent on others.

Working problems is your most important learning technique, but the exams will also draw on the ideas and key examples given in class. Take careful notes during the lectures, or if this does not work well for you, obtain them from someone else. The lectures provide your road map to learning the subject.

Always use correct mathematical notation. (Example 1: write the "=" sign only between two mathematical objects that really are equal-- some students just seem to use it as a random space filler. Example 2: always write "sin(x)" and "cos(x)", never just "sin" and "cos", which makes "sin cos" ambiguous-- does it mean the product "sin(x) cos(x)" or the composition "sin(cos(x))" ?) Good notation will help keep you on the right track during exams, but you will only use good notation in a stressful exam situation if you have been using it habitually on your homework problems.

Nothing is more important than staying completely caught up; cramming is even less effective in mathematics than in other courses. If you need help, go to office hours or arrange an appointment immediately; do not compound your difficulties by delaying.
