**Instructor:**

M. Randall Holmes

**Schedule:**

We meet in MP 308 Monday, Tuesday, Wednesday and Thursday, from 11:50 am 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 an old syllabus for a different course; please
call any editing errors caused by this to my attention.

**Title of Course:**

Math 333: Differential Equations. This is section 031.

**Textbook:**

Polking, Boggess and
Arnold, *Differential equations with boundary value problems.*
A new edition has been ordered and has not yet arrived at the
bookstore as I write this on May 27^{th}.
I advise against ordering the book elsewhere in spite of the obvious
attractions, as you are likely to get the wrong edition and so have
all the homework problem numbers wrong. I will **not**
promise any special services to students who put themselves in this
position. Really. Not.

**Dates:**

The add deadline (and deadline for dropping without a W) is June 10. The drop deadline is June 29. Petitions to drop classes after this date are usually unsuccessful. Dates for in-class exams: June 18, July 2, July 16, July 30. All exams are on Thursdays; the last is the final. The final exam will be Thursday, July 30, 2009, at our regular time in our regular room.

**Calculators:**

We may sometimes have occasion to use calculators in class. Use of a plain scientific calculator (without graphing or symbolic computation capabilities) will be allowed on tests. Make sure you have such a calculator if you want to use a calculator on tests. 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.

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

I expect to give three in-class exams this term and the final. There will not be 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. 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). I will not be on campus at all on
Fridays.

**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 :-)
