Math 285 Section P1 Fall 2015

Differential Equations



Announcements:

Room: 156 Henry Bldg.

Time: TTh 11:00 am - 12:20 pm

Lecturer: Eduard-Wilhelm Kirr

Midterm 1: September 17, in class. Counts for 20% of your grade.

Midterm 2: November 5, in class. Counts for 20% of your grade.

Final Exam: 8:00-11:00 AM, Friday, December 11, in 156 Henry Bldg. Counts for 40% of your grade.

Test Policies: You may not use books, notes, calculators or computers during any of these tests. Make up tests will be given only if you present written evidence, as soon as possible, that you did (or will have to) miss an exam for a legitimate reason, e.g. illness or family emergency. Travel and leisure plans are never a legitimate reason.

Computing: Math 285 usually has a computer component for which the class meets in a lab. Due to logistical issue I will drop this requirement. However, understanding how numerical methods/computer simulations try to resolve differential equations remains part of the syllabus. The simulations will be done in class by me but I recommend that you familiarize yourself with a programming language and try to run the simulations independently.

Syllabus: Basic introduction to the study of differential equations; topics include: first order ODE's, higher order linear ODE's, Fourier series and separation of variables. Click here for more details.

Text: C. H. Edwards and D. E. Penney, Differential Equations and Boundary Value Problems: Computing and Modelling , Custom Edition for the University of Illinois at Urbana-Champaign, Pearson Custom Publishing, 2008. Note: This custom edition is taken from Edwards and Penney, Differential Equations and Boundary Value Problems: Computing and Modelling, Fourth Edition. It is identical to the fourth edition except that Chapters 5, 6, 7, and 8 have been removed. If you would prefer to use the full fourth edition, this should not be a problem. The full fourth edition is the standard text for Math 286.

Homework: Assignments will be given weekly (about 12 total). I will not collect or grade the homework. However, problems from homework will make up the weakly quiz, see below. I strongly recommend that you carefully work out each problem and write up the solution using the model exercises presented in class. If you have any questions you should ask them in class or come to the office hours. Check back this page for actual assignments.

Quizzes: There will be a 10-15 minutes quiz almost every week. They will count for 20% of your grade. You may not use books, notes, calculators or computers during any of these quizzes. Each quiz will contain problems selected from the current homework assignment. Make up quizzes will not be given but your lowest two quiz scores will be dropped.

Miscellaneous: Your assignments and exam scores will be stored on a secure server. You can access your scores using your NetId and Password by following the Score Reports link found here . The algorithm on the server also gives you a letter grade based on your current scores and the curve: A for 90% and up, B between 80% and 89.9% , C between 70% and 79.9%, D between 60% and 69.9% and F below 60%.

Lecture Notes: The mht format has colors and other enhancements like an ActiveX control that you should allow for easy navigation. If your browser cannot open it use the pdf file:
