**Instructor:**

M. Randall Holmes

**Schedule:**

We meet in ILC 404 (Interactive Learning Center) Monday, Tuesday, Wednesday and Friday, from 12:40 pm to 1:30 pm.

**Office and Hours:**

Office: Math/Geology 240A. Hours: To be determined after consulting you all. See ``open office policy'' below.

**Telephone:**

My office telephone number is 6-3011 (426-3011 from off-campus). My home telephone number is 345-2899: students are welcome to call me but please no calls after 8:30 pm any day or between 6 pm Friday and noon Sunday.

**Electronic Information:**

e-mail: holmes@math.boisestate.edu WWW (web page): http://math.boisestate.edu/~holmes

I read my e-mail constantly and respond promptly. An electronic
version of the syllabus, which will include homework assignments,
will be accessible from my web page. **The electronic version is the
official syllabus, and any changes will be posted there and not
distributed on paper**. Please note that this document was
obtained by editing the fall 2010 syllabus for this course; please
call any editing errors caused by this to my attention.

Electronic announcements for this class (and announcements to both classes) will appear in three different ways. Announcements tied to specific assignments will appear on the class schedule. Notice that the class schedule includes assignments for both classes: you should be able to tell which ones go with Math 333. Some announcements, especially documents such as old sample tests, will appear on my main web page where the pointer to this syllabus appears. Occasionally I may send e-mail to the entire class. Make sure either that you read your Boise State e-mail regularly or forward your Boise State e-mail to an account you do read regularly.

**Title of Course:**

Math 333: Differential Equations. This is section 002.

**Textbook:**** **Polking,
Boggess and Arnold, *Differential equations with boundary
value problems, *second edition.

**Dates:**

The add deadline (and deadline for dropping without a W) is Jan 31. The drop deadline is Feb 28. Petitions to drop classes after this date are usually unsuccessful. Dates for in-class exams: Feb 18, Mar 18, Apr 8, Apr 29. All exams are on Fridays. The final exam will be Monday, May 9, 1-3 pm, in our usual room. Please note that the final exam in any class I teach is open book plus one standard-sized sheet of notebook paper with whatever you want written on it (yes, on both sides). The first three exams are closed book, no notes.

**Calculators:**

We may sometimes have occasion to use calculators in class. Use of a plain scientific calculator (without graphing or symbolic computation capabilities) will always be allowed on tests. Make sure you have such a calculator if you want to use a calculator on tests. It's possible that a better calculator will be allowed on later exams and/or the final, but don't count on it; I will advise you if this happens. You may not use cell phones or PDAs (such as Palm Pilots or Pocket PC's) as calculators during any exam. No exceptions will be made.

**Homework:**

Homework will be assigned regularly. If you hand homework assignments in to me 2 days after they are assigned, I will correct and return them. Questions about homework will be answered at the beginning of each period. Homework handed in late may or may not be attended to. We might have some computer labs in this class: if we do, they will fall under the homework classification.

**How Your Course Grade Will Be Computed:**

I expect to give four in-class exams this term and the final. I do not usually give review days for exams other than the final, though I will be willing to take questions about exams during the usual time for homework discussion (within reason); the review day for the final might disappear itself. Notice though that I have put review days in on my schedule: but if we go slowly they will disappear. Exams will generally be linearly scaled so that the median grade in the class corresponds to a mid-range C (75 percent) unless I am seriously dissatisfied with overall class performance. Each exam and the total homework grade is worth 100 points. The final counts 200 points; your percentage grade on the final may replace the lowest of the other four grades (in-class exams and homework) if this helps you. 90 or above is an A; 80 or above is a B; 70 or above is a C; 60 or above is a D; lower grades are F (after any scaling).

**Eligibility for this Class:**

No exceptions will be made. If the computer tells me that you don't meet prerequisite or placement exam standards for this course, I will free your seat for someone who does meet them (in fact, the office staff now does this before it even comes to my attention).

**Attendance:**

Attendance will not be taken except on the first two days. If you do not attend this class on at least one of the first two days, I will exercise my option to have you administratively withdrawn (though not until after the third day of classes to give you one more chance to show up).

**Open Office Policy:**

My office hours for these classes are
to be announced. I will almost always be in my office at the
officially scheduled times, and I will try to warn you when I will
not be. If I am in my office during a posted office hour, I am
available to help you. Don't assume that these are the only times
when you can get help! I am never offended by a student asking me for
help if I am in the office (though I may help only briefly if I am
*very* busy). My other class meets 9:40-10:30 am MWF;
there is no guarantee that I will be on campus at all on Thursdays.

**Late Work and Makeups:**

Makeups for exams will be possible, and should if possible be arranged in advance of your absence.

**Academic Honesty:**

The penalty for cheating (defined as looking at another student's paper or unauthorized use of books or notes during an exam) will be a grade of zero (0) on the relevant exam. A repeat offense will mean an F in the course.

**Courtesy Issues:**

Cellular phones must be turned off
during class. If there is a **good** reason that you must await a
phone call during class, please inform me in advance and minimize the
disruption by sitting near an exit. Cell phones **must** be turned
off (no exceptions whatsoever) during an exam. You do not need to
contact me if you are missing class or if you need to arrive late or
leave early; but I do need you to enter or leave the class quietly in
either case. Of course, you do need to contact me, **preferably in
advance**, if you are missing an exam.

**Definitions:**

The word ``yesterday'' is defined to mean the previous class session; the word ``tomorrow'' is defined to mean the next class session, unless I specifically say otherwise :-)
