Instructor and Meeting Times |

Note that you do not need an appointment to attend regularly-scheduled office hours. If you have a conflict you may make an appointment to meet outside those times.

Course Description and Objectives |
---|

Theory and application of linear ordinary differential equations: homogeneous and nonhomogeneous linear equations, initial and boundary value problems, exact equations, variation of parameters, Euler equations; solutions of non-linear ordinary differential equations of the first order and second order; power series solutions; system of linear equations.

**Course objectives:** This is a course in Ordinary Differential Equations. The word "ordinary" means that the equations considered in this course will only have one independent variable. After this course students should understand the basic terminology of differential equations, understand the various methods of solving linear differential equations, and how to apply them to model various systems. Students will also learn the basic theorems that guarantee the existence and uniqueness of solutions to various differential equations.

Homework |
---|

Problems will be assigned regularly on the homeworks tab of this page. Students are expected to work through these problems to practice the material, and are encouraged to ask questions in office hours regarding any difficulties they encounter. These will not be collected, however these problems or problems similar to them are likely to appear on quizzes.

Occational **written assignments** will also be given, which will be listed on the schedule tab of this page. These assignments will explore concepts more in depth, including applications and use of technology. Solutions to these assignments must be written up carefully. These written solutions must be turned in at the beginning of class to receive full credit.

Students will be asked to participate in class, by presenting solutions to homework problems and asking/answering questions.

Expect to spend a substantial amount of time studying, working on homework and preparing for the course. The general rule is two to three hours outside class for each hour inside; this translates to about 6-9 hours of homework and personal study per week.

Additionally, each student is responsible for writing up notes describing what was covered during two lectures during the term. These notes should be written up clearly **using latex** and submitted to the instructor within a week of the class period. Students are also encouraged to include additional examples/explanation. Notes will be posted for use by the rest of the class. Sign up for class periods here. Note: these notes will count as one written assignment.

Regular **quizzes** will be given in class, generally on Mondays. These quizzes will cover material from the homework assignments. The lowest quiz score (including one missed for any reason, excused or unexcused) will be dropped.
Instead of a Third midterm exam there will be a project instead. More details to come.

Exams |
---|

There will be ~~three~~ two midterm exams and a final exam covering the material presented in lectures, readings and on homework assignments. The schedule for the midterm exams is tentative.

Midterm 1 | Midterm 2 | Final Exam | |
---|---|---|---|

Monday March 2nd | Wednesday April 22nd | Wednesday, May 13th 5:15--7:15pm |

Evaluation |

Disabilities and Religious Observances |
---|

Towson University is committed to providing equal access to its programs and services for students with disabilities, Students with disabilities should visit the Accessibility and Disability Services Web page, to learn about how to arrange for any appropriate accommodations. It is the student's responsibility to let the instructor know when he/she is a student with needs in this area. A memo from Disability Support Services (DSS) authorizing your accommodations will be needed.

If you have a religious observance that conflicts with your participation in the course, please meet with me before the end of the second week of the term to discuss appropriate accommodations.
