Math 3301 – Differential Equations
Class Notes These notes are NOT a substitute for attending class. I've tried to make them as complete as possible, but often a good question will arise in class that I didn't think about while writing the notes. So, if you skip class you will not get the results that discussion. Also, the examples given in the notes may or may not be the same as the examples given in class. This will depend upon the section that we're covering on any given day. Exam Schedule When I have finalized an exam date I will change the color of the date to red. At this point you will know that the exam will fall on that date. Click here to see my makeup policy for this class.

Grades & Distributions A : 100% 90%, B : 89%  80%, C : 79%  70%, D : 69%  60%, F : 59%  0% The "exam grades" are included only for reference purposes so you will know how you are doing in the course to that point and DO NOT in any way influence the final course grades. To make it a little easier to read the results I've also include the point range/scale needed for each grade based upon the standard percentage scale listed above. I've got a very simply policy for computing final grades. At the end of the semester I add up your total points and divide that by the total number of possible points and then compare that percentage to the standard scale given above and assign a grade accordingly. I do not use any kind of fancy weighting system and I rarely scale the grades. On those few occasions that I do scale the final grade it is never more than a percentage point or two. I've also complied all of the exam results here so that they are in one place. [Show Exam Results] [Show Grade Distributions]Exam Results

Grade Distributions
Note that the number of student here after each exam may differ from that listed in the exam results. The totals here include all students still enrolled in the class instead of just those that took each exam.
Homework Assignments/ Due Dates Each homwork set generally consits of my own problems. I have, on very rare occasions, used problems out of a text book. When I do use a problem out of a text book I will put the problem in its entirety in the homework set and the text book will NOT be needed for the problem. Note as well that for good or bad my own problems tend to be harder (in general) than the average text book problem. In most classes I will also post complete solutions to each homework set. IF solutions have been made available for download for a given set of homework there are a couple of things to note. First, the solutions may not have all the graphics that were in the solutions handed out in class due to the difficulty of getting some of the graphics into the document. Second, typically those that I graded are given first, with point values, and those that weren't graded are given last. Last, due to time constraints I don't always include every step in the solutions. I will always put in what I consider to be major steps and the answer will always be given. It will up to you to fill in any missing steps. In order to view the homework sets and solutions you will need to have the Adobe Reader installed on your computer. You can download a copy here. Our lab in Lucas 209 already has the Adobe Reader installed so you can always use one of the computers there to view the homework sets. Disclaimer : While I make every effort to make sure that the homework sets available here and the due dates are accurate, I will on occasion have a typo in the homework set, change the due date and/or inadvertently put the wrong due date here. If there is ever a discrepancy between the due date listed here and that given in class the due date given in class is the official due date. In the case of typos I will always announce the typo the very next class period after finding the typo. I will also make every effort to get the typo corrected here, however it may take me longer to get the typo corrected here. It is your responsibility to know the correct due dates and/or be aware of any typo fixes that I may have announced in class.
