### Syllabus

**Instructor**: Abraham Engle**Time and Place**: MWF 2:30 - 3:20pm Mechanical Engineering Building (MEB (Links to an external site.)) 238**Office**: Padelford C-430**Office Hours**: After class, by appointment, 3:30-5:30PM Wednesdays in the Math Library**Email**: aengle2@uw.edu

**Grader:** Xinyue Peng**Email:** xinyue07@uw.edu

**Prerequisites**: 2.0 or higher in both Math 307 and Math 308 required.

**Overloads:** There will be no overloads in this course. If you are not yet enrolled then you should keep checking the math enrollment summary (there's a link on the top left of the math time schedule) for drops.

**Overview**: Please see the Overview tab

**Textbook: ***Differential Equations with BVP* (University of Washington custom Math 309 version) or, equivalently, *Elementary Differential Equations and Boundary Value Problems*, 9th Edition by Boyce and DiPrima. 8th Edition may work as well, however be aware that some of the problems may be different. Prof. Arms provided a list of changes in the text (Links to an external site.). Ideally you should doublecheck that you are doing the correct problems, by looking at the 9th edition at the library, or from one of your classmates.

**Grading**: Your grade is computed as a convex combination of the following categories:

Homework: 20%

Quizzes: 20%

Midterm: 30%

Final: 30%

I may change these weights in the future, but only in a way that increases in the class median.

**Calculators**: No calculators with graphing capabilities or calculators that can symbolically integrate/differentiate. Scientific calculators are allowed on quizzes and on both exams.

**Homework**: There are seven homework assignments this quarter, and they are all exercises in the textbook. A few randomly chosen problems will be graded for correctness, while the remaining problems will be graded for completeness. Homework is due in class on Fridays and is returned the following week. Each student receives two late days. One use of a late day extends the due date of one homework assignment to the beginning of the following class period (that Monday). The catch is that I will grade your homework, and I will grade every problem. You are free to stack your late days (so you must hand it in at the start of class the following Wednesday), but with homework due the following Friday, I would not recommend it. You are also free to turn in homework late after using your late days, but again I will grade every problem and deduct 30% per day late from the total after grading. Please do not fall behind! One last thing about homework: __please staple it!__ I've instructed the grader to deduct a point for unstapled homework. I will not provide a stapler in class.

**Quizzes**: There are four scheduled quizzes, and I will drop your lowest one. Quizzes are announced and given on Fridays, and they are twenty-five minutes in length. You will not need and are not allowed a formula sheet for the quizzes. There are no makeup quizzes without a documented illness.

**Midterms**: There will be one midterm this quarter. There will be no homework due the following week. You are allowed a single 8.5" x 11" cheat sheet (front and back) for the midterm. The problems will come from old exams and from the textbook.

**Final**: The final is set by the university: Tuesday, March 15, 2016, 230-420 pm, MEB 238. It will be cumulative. You are allowed a single 8.5" x 11" cheat sheet (front and back) for the final as well. The final will be more challenging than both midterms.
