Description of Course: This course covers basic theory and methods of solution for differential equations. The major part of the course deals with linear differential equations and systems of linear differential equations. Laplace transforms are among the tools introduced for the solution of these linear differential equations.

Objectives and Goals of the Course: We will cover most of chapter 1 - 4, 6, 7 and some supplementary material as time allows. You should read all sections/handouts/web material corresponding to covered material and/or assigned problems.  There may be test questions related to this reading even if not covered in class.

Text: Boyce and DiPrima, "Elementary Differential Equations and Boundary Value Problems," 8th or 9th edition (see note).

 HW & Quizzes: 16% 90% <= A- < 91% <= A Computer Projects: 10% 80% <= B- < 81% <= B < 89% <= B+ < 90% Exam 1 (Sept. 24):  22% 70% <= C- < 71% <= C < 79% <= C+ < 80% Exam 2 (Nov. 12):  22% 60% <= D- < 61% <= D < 69% <= D+ < 70% Final ( 9:45 A.M. Thurs Dec. 16): 30% F < 60%

GRADING & EXAMS:  THE ABOVE EXAM DATES ARE TENTATIVE. All work must be shown in order to receive credit.  This holds for all exams including the final, all quizzes, homework and computer projects.  Important note:  If no work is shown, you may receive zero credit even if your answer is correct.

2 exams and a final will be given.  Locations TBA.  You are required to bring identification to all exams.   Calculators may NOT be allowed.  You are required to pick up your exams and keep them until the end of the semester.  The final exam will be cumulative.

THERE IS NO CURVE IN THIS CLASS, but improvement may be taken into consideration.

If there is a mistake in grading, you must report this mistake within one week from when the exam, homework, etc. has been handed back to the class (whether or not you picked up your exam, homework, etc).

More on computer projects
: It is not assumed that you are an expert in any particular operating system or computer algebra software in advance. Web resources connected with the computer assignment will offer help on using Maple on the machines in the Mathematics Department's Computer Lab (B5 MLH), which run Linux. Things should look roughly the same on the machines in the Engineering labs 1220 and 1231 SC. You are free to use another platform (e.g. PC, MacIntosh) and/or computer algebra package (e.g. Mathematica) if you wish; however, there will be no support (helpful handouts, etc.) on these.

Attendance and absences: Your attendance at each scheduled class meeting and problem section is expected.  You are  responsible for material covered in class and announcements made during class; these may include changes in the syllabus.

You may collaborate with other students on the homework;   however, each individual student is responsible for turning in your own homework in your own words.  Copying is not collaboration and will be prosecuted under scholastic dishonesty.  Any significant collaboration should be acknowledged.

The University policies on scholastic dishonesty will be strictly enforced.
