Prerequisites

Single-variable calculus (Math 0420, 0450, or equivalent) including Taylor series, linear algebra (Math 1180, 1185 or equivalent) including eigenvalues and eigenvectors.

Textbook

* Polking, Boggess and Arnold, Differential Equations with Boundary Value Problems, second edition, Pearson Prentice-Hall

* Polking and Arnold,Ordinary Differential Equations using MatLab, Third Edition, Pearson Prentice-Hall (Available at The Book Center on Fifth Ave.)

Other Materials

You will need some MatLab add-on software for differential equations. It can be downloaded from http://math.rice.edu/~dfield/  at Rice University.

Java applets for pplane and dfield programs can be found at http://math.rice.edu/~dfield/dfpp.html .  They run in your browser without the need for Matlab software.

Grading Scheme

Homework Assignments: 20%

Two Midterm Exams: 40%  (20% each)

Final Exam: 40%

Exam Policies

Exam dates will be announced ahead of time. Any student with a serious conflict should alert the instructor ahead of time, before the exam date, to discuss arrangements and should be prepared to show documentation establishing validity of the conflict. The time and place of the departmental final exam has been scheduled by the registrar. According to the policies of the Department of Mathematics, your final grade may not exceed your final exam grade by more than one letter grade.

Academic Integrity

Cheating/plagiarism will not be tolerated. Students suspected of violating the University of Pittsburgh Policy on Academic Integrity will incur a minimum sanction of a zero score for the quiz, exam or paper in question. Additional sanctions may be imposed, depending on the severity of the infraction.  On homework, you may work with other students or use library resources, but each student must write up his or her solutions independently. Copying solutions from other students will be considered cheating, and handled accordingly.  The schedule and a list of homework problems will be posted below.  Homework is due at the beginning of a class one week after it was assigned.
