ORDINARY DIFFERENTIAL EQUATIONS AND LINEAR ALGEBRA 1. General Information Course: Math 211-002, Fall 2007 Instructor: Sabin Cautis Office: Herman Brown 432, x4053 Office Hours: – Sabin Cautis in HB 432: Thursday 4-6pm. – Jon Chaika in HB 42: Wednesday 8-9am and Thursday 10:45-11:45am. • E-mail: scautis@rice.edu • Website: includes syllabus, course schedule and homework assignments http://www.math.rice.edu/∼sc5/math211/ • Text: Polking, Boggess and Arnold, Differential Equations, 2nd edition. Poling and Arnold, Ordinary Differential Equations using MATLAB, 2nd edition. Note: Any student with a disability requiring accommodation in this class is encouraged to contact me after class or during office hours. Additionally, students should contact the Disabled Student Services office in the Ley Student Center. Homework: Homework will be assigned every week on Tuesday (with the exception of the first week) and due the following Tuesday in class. Homework is not pledged. You may get help from any source. However you are strongly encouraged to attempt the problems yourself before seeking assistance. Any written work submitted must be your own. Your submitted work must be stapled together and should have your name on every page. I will accept homeworks dropped off at my office before 1PM on the day it is due, after that homework will be late. Late homeworks will not be accepted for credit. Tests: There will be two midterm exams and a final exam. The tests will be closed book. Calculators will not be allowed. The dates for the two midterms are: October 4th and November 8th. The exams will be held during the 8:00-9:15 AM time period. The rooms for the exams will be announced in class. Project: Topics for the project will be discussed later in the term. The project itself will be due on the day of the final exam. Grades: Grades will be computed as follows: Homework: 25 % (the lowest homework score will be dropped), Midterms 30%, Project 10%, Final Exam 35%. Help Sessions: Mondays 7-9pm in TBA. Teaching Assistants: • TBA TBA@math.rice.edu Final Exam Policy: It is the policy of the mathematics department that no final may be given early to accomodate student travel plans. We will not know when the final in this course will be scheduled for some time. Therefore, if you should make plans to travel before the end of final exam period, and it turns out that the final for this course is after your scheduled departure date, you will have to choose between keeping your plans and receiving zero for the final, or incurring the costs for changing your plans and taking the final at its scheduled time. Thanks for your understanding. Note: Any student with a documented disability seeking academic adjustments or accommodations is requested to speak with me during the first two weeks of class. All discussions will remain as confidential as possible. Students with disabilities will need to also contact Disability Support Services in the Ley Student Center. • • • • 1 2 ORDINARY DIFFERENTIAL EQUATIONS AND LINEAR ALGEBRA 2.
