Go Cyclones!

The final exam will be a comprehensive exam over the entire
course. It will be given on Wednesday of exam week:

Date: Wednesday, May 7th
Time: 12:00 - 2:00 pm
Place: Lebaron 1210


Although the final exam will be cumulative, only problems from
the sections listed below will be on the exam. This is still
and extensive list. The problems listed are representative
of the problems that will appear on the exam. A table of
Laplace transforms will be provided.

Email, Office Hours, and Grades

The office hours are intended to be used to help students with questions about mathematical problems. They can also be used to discuss exam scores and a student's progress in the course. Email will not be used for these purposes. As a standard policy, no grades or exam scores will be sent out to students via email or given over the phone.

Course Description (from ISU Catalog)

Math 266, Elementary Differential Equations, Cr. 3. Prereq: Grade of C- or better in Math 166. Solution methods for ordinary differential equations. First order equations, linear equations, constant coefficient equations. Eigenvalue methods for systems of first order linear equations. Introduction to stability and phase plane analysis.

Math 267, Elementary Differential Equations and Laplace Transforms, Cr. 4. Prereq: Grade of C- or better in Math 166. Same as 266 but also including Laplace transforms and series solutions to ordinary differential equations.

Textbook

Fundamentals of Differential Equations and Boundary Value Problems (6th edition) , by Nagle, Saff, and Snider .

Fundamentals of Differential Equations (8th Ed.) , by Nagle, Saff, and Snider .

Either version is okay. These are identical except for the 3 additional chapters in the version that includes boundaray value problems.

Grading Policy

Course grades will be determined from student performance on exams and quizes. There will be four exams: three 50 minute in-class exams and a final exam. The three in-class exams, which are indicated on the syllabus above, will be given during the hour normally used for lecture. These exams will be written by the instructors, and will test only the material covered since the previous exam. In contrast the final exam, which will be given during the week of final exams, will be a departmental cummulative exam. All of the exams will consist of problems similar to the homework problems assigned throughout the semester.

Homework will be assigned on a daily basis. The daily homework assignments will not be collected nor graded. However, it is important for learning and understanding that these problems be done as they are assigned. They should be thought of as required for success in the course (see Strategies for Success ).

The exams will be weighted as follows:

Exam 1 100 points
Exam 2 100 points
Exam 3 100 points
Final Exam 150 points
  --------
Total 450 points

All quizzes will be announced ahead of time and usually weighted as 25 points, although the weighting may vary. The final course grades will be determined by the percent of points earned out of the total number of points (i.e. exams + quizzes). A straight scale will be used so that A's, B's and C's correspond to the percent ranges 100-90, 90-80 and 80-70 respectively. 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.

Strategies for Success

Math 267 is an introductory course on differential equations which presents solution methods. Like the calculus courses it is a problem solving course. Most if not all of the homework exercises are computational problems. The same can be said about the exam questions, which will be based on the suggested homework problems. Like any other skill, problem solving requires practice. And like any other skill, the more you practice the more proficient you become. In order to be successful in this class there are two time commitments on your part that are essential: i) attend the lectures regularly and ii) stay current in completing the homework assignments . If you have trouble with the homework you should seek help immediately so that you do not fall behind. The course moves quickly and falling behind may very well spell disaster. There are several sources of help.

Sources of Help

Disability Resources

Iowa State University complies with the American with Disabilities Act and Section 504 of the Rehabilitation Act. If you have a disability and require accommodations, please contact the instructor early in the semester so that your learning needs may be appropriately met. You should contact the Disability Resources office for information on appropriate policies and procedures. The Disability Resources office is located on the main floor of the Student Services Building, Room 1076; their phone is 515-294-6624.
