Text: Introduction to Ordinary Differential Equations (4e), Shepley L. Ross (Wiley).

Prerequisites: You may enroll in Math 3305 if you have completed Calculus II (MATH 2414).

Course Description: This course is a study of ordinary differential equations, with emphasis given to equations of the first order, linear equations, and solution by series.

Make-Up Policy: If you must miss class for a legitimate reason, such as participation in a university activity, hospitalization, etc., I will grant a make-up for any missed work, provided that I am given sufficient notice of said absence and satisfactory evidence that it is legitimate. Oversleeping, for example, does not constitute a legitimate absence. If you’re not sure, ask.

Assessment: Your grade for this course will be based on homework, quizzes, two in-class exams, a project, and a final examination.

• Homework will be assigned and collected regularly throughout the semester. Homework assignments must be turned in as you enter the classroom on the day it is due. Late homework will only be accepted if approved ahead of time by the instructor, and this will only happen in the case of excused absences.
• (At least) one homework score will be dropped at the end of the semester.
• Solutions to homework problems will be provided in class, and you are expected to check your work against these solutions. I will not necessarily grade every problem you are assigned, so it is important to check your answers.
• Homework must be written up neatly and either stapled or paper-clipped.
• Quizzes will be given frequently and your lowest quiz score will be dropped. You will not necessarily know ahead of time that we are having a quiz that day, so prepare to be in class on time every day that we are scheduled to meet.
• The final project will be due on the last day of classes in May. We will discuss the nature, length, etc. of this project in more detail within the first few weeks of classes. This project is intended to expose you to material we have not seen in class, or more depth regarding material we have seen. This is a written project (you will not have to give a presentation!). You will have considerable freedom (and help if you need it) choosing a topic, which can be either theoretical or applied. This project must be done individually.
• The final examination is cumulative.

Tentatively, I expect the grade distribution to be as follows:

                        In-class exams (2 @20% each):               40%

                        Homework                                             10%

                        Quizzes                                                            10%    

                        Final project                                          20%

                        Final examination                                  30%

Disability Statement: If you have a disability, including a learning disability, for which you request an accommodation, please contact Ida MacDonald in the Disability Support Services offices so that appropriate arrangements may be made. In accordance with federal law, a student requesting accommodation must provide documentation of his/her disability to the Disability Support Services counselor. For more information, call or visit the Student Services Centre, Room 111 in the University Centre. The telephone number is 566.7079 (TDD 565.5579).

Social Security Statement: It is the policy of The University of Texas at Tyler to protect the confidential nature of social security numbers. The University has changed its computer programming so that all students have an identification number.

Grade Replacement: If you are repeating this course for a grade replacement, you must file an intent to receive grade forgiveness with the registrar by the 12th day of class.  Failure to file an intent to use grade forgiveness will result in both the original and repeated grade being used to calculate your overall grape point average. A student will receive grade forgiveness (grade replacement) for only three (undergraduate student) or two (graduate student) course repeats during his/her career at UT Tyler. (2006-08 Catalog, p. 35)
