This course is intended to introduce students the basic procedures and techniques for solving ordinary differential equations. First order equations, linear equations, and constant coefficient equations. Eigenvalue methods for systems of first order linear equations. Introduction to stability and phase plane analysis. Laplace transforms and series solutions to ordinary differential equations.
á Textbook: Fundamentals of Differential Equations and Boundary Value Problems, 6th edition, by Nagle, Saff and Snider
á Course Syllabus: Tentative schedule of the lectures.
á Homework: Homework will be collected weekly. It is due usually on Tuesday. Late homework will not be accepted. Please keep in your mind that doing homework makes you familiar to the fundamental concepts and basic techniques and deepens your understanding. Its importance can never be over-emphasized. Please feel free come to the instructors whenever you need help.
á Exams and Quizzes: There will be 3 in-class exams, 4 quizzes and the final exam (see the syllabus for the dates). Calculators are allowed during exams. But you must show your work on the paper step by step to get full credit. No make-up, except for special circumstances. If an emergency causes you to miss an exam, contact the instructor as soon as possible.
á Course Grading: Course grades will be given based on the homework (10%), three in-class exams (60%), quizzes (5%) and the final exam (25%). Here is a tentative grading scale: A over 90%; B over 80%; C over 70%; D over 60%. At the discretion of the instructor these percentage cut-offs may be lowered to allow for "curving" of the overall difficulty of the exams. However they will not be raised for any reason, and in this sense are guaranteed grade ranges. Plus/minus grading will be used.
á Software: There will be some limited use of MATLAB. Instructors will provide some basic information about how to use it at the appropriate time. You should find a computer system that you have easy access to on which MATLAB can be run.
á Disability Accommodations: If you have a disability and require accommodations, please contact the instructors early in the semester so that your learning needs may be appropriately met. You will need to provide documentation of your disability to the Disability Resources (DR) office, located on the main floor of the Student Services Building, Room 1076, 515-294-6624.
