Text:
Fundamentals of Differential Equations and Boundary Value Problems, 6th Edition, by R. Kent Nagle and Edward B. Saff. [If you have an earlier edition, that's fine, but make sure that you turn in the right HW problems corresponding to the 6th edition; in the assignments I will also indicate the numbers of the 5th edition]

Course Objectives:
Continuation of the study of ordinary differential equations (ODE's); power series as solutions to certain ODE's leading to special functions; linear systems and their solutions; 2-dimensional (non)linear systems, phase-plane analysis and stability theory; Sturm-Liouville boundary value problems.

Topics:
We will cover chapters 9, 12, 8 and 11 of the text (in that order).

Grading:
Course grades will be determined by your performance on 4 graded homework assignments and 2 in class exams.
Late HW is not accepted.
The weights are: 12.5% for each HW, 25% per exam.
In addition to the graded HW, there will be weekly HW assignments which are not collected nor graded.

Grading Scale (maximum of 100%):

A: [>=85%]   B+: [76-84%]     B: [70-75%] C+: [65-69%]   
C: [60-64%]   D+: [55-59%]     D: [50-54%]    E: [<50%] 

Guidelines, tips, How to study and prepare for exams? etc:
First, there are no make-up exams, unless there is a documented medical emergency, which is announced at least one day prior to the exam.
Although the weekly HW assigments will not be collected, I strongly encourage you to work on these problems in a timely fashion. They will prepare you for the next classes, deepen your understanding, and reveal where you have certain deficiencies with the material covered up to that point. My experience is that students who don't keep up with these weekly HW's quickly find themselves behind and spend the rest of the semester "catching up". Don't let it get that far!
In parallel you should also attempt to solve the graded HW assigments. I urge you not to postpone working on these problems until a few days before they are due as they will generally require substantial time for you to solve. As a guideline I would say that each problem will take you about an afternoon or evening, and I expect there will be about 5 to 6 problems per assignment. The problems on the exams will be very similar in nature to those assigned, so you can draw your own conclusions ...
I am not taking attendance for this class, but some material covered will not be in the textbook. So my personal opinion is that showing up for class is a good idea. It is each student's responsibility to know what exactly has been taught. In particular, in general there will not be any handouts of lecture notes on such additional topics, and the instructor will not teach this material again during office hours or via email to students who have missed a class.
