Calculator: You will need a scientific calculator that graphs functions. The recommended models are TI-82, TI-83, TI-83 Plus, TI-84, TI-84 Plus, TI-89, TI-89 Titanium and TI-92. Please do not use a TI-nSpire for this course. These recommended calculators may be used on tests and on the final examination. Text-capable or networked devices are prohibited.

Objectives: To develop elementary modeling and problem solving skills in ordinary differential equations.

Outcomes: Course participants should be able to discuss topics in differential equations, as well as use modeling techniques to answer basic questions.

Assessment: The course grade employs a total of 500 points. Each student’s grade will be based upon the percentage of points earned according to the following scale.

  Tests (2 @ 100 pts. ea.) 200 pts.  
  Homework (5 @ 30 pts. ea.) 150 pts.  
  Comprehensive Final Examination 150 pts.  
  A - 90% 450 - 500 pts.  
  B - 80% 400 - 449 pts.  
  C - 70% 350 - 499 pts.  
  D - 60% 300 - 349 pts.  
  F <= 299 pts.  

  1. Tests   There will be two 100 point tests and a 150 point comprehensive final examination. You’ll need to show your work in writing on test problems in order to receive full credit. Problems presented on tests may not be exact ‘clones’ of problems found in the text, and some independent thought may be required. If you must miss a test, you’ll need to make an explicit agreement with the instructor in advance of the scheduled test date for a make-up test. Tests will occur as per the attached class  schedule . Phone messages relating a student’s inability to attend a test will not be accepted as a rescheduling arrangement. YOU MUST TALK TO THE INSTRUCTOR BEFORE THE TEST TO ARRANGE A MAKE-UP TEST.

  2. Homework   Daily homework assignments will not be turned in for a grade. However, homework review/problem solving sessions based on this material will be held at each class meeting. Five short homework assignments requiring more careful write-ups will be assigned and turned in for 30 points each. Homework assignments must be turned in on the day the instructor asks for them in class. Homework that is turned in late will be subject to penalties. Homework turned in more than four weeks after the due date will receive no credit.

  3. Final   The  final examination  will be written by the Mathematics Department. The final examination will occur at 16:00 - 17:55 p.m. Wednesday May 11. Phone messages relating a student’s inability to attend the final examination will not be accepted as a rescheduling arrangement. YOU MUST TALK TO THE INSTRUCTOR BEFORE THE TEST TO ARRANGE A MAKE-UP TEST. DO NOT SCHEDULE PERSONAL TRAVEL PLANS THAT MAY CONFLICT WITH THIS DATE.

  4. Attendance   Class attendance is expected. Attendance will be not be formally recorded, and it is not included in grading procedures. When you miss a class, it’s strongly recommended that you contact other students or the instructor to get up to date on announcements, homework, etc.

  5. Assignments   Students should read all sections of the textbook mentioned in the class schedule, and are responsible for this material. It’s very important to attend class regularly and extremely important to work through daily homework assignments in a timely fashion. Keep in mind that it can be very difficult to catch up once you fall behind on the course material.

  6. Accommodations   Students with disabilities are personally responsible for arrangements to use physical or academic accommodations associated with this course. Failure to make those arrangements with the instructor and the Coordinator of Accessibility Services in a timely fashion may negatively impact your grade. Students with registered learning, physical or psychological disabilities, who require accommodations for this course should contact both the instructor and the Coordinator of Accessibility Services: Dr. Fink at (330)684-8767 or, to begin delivery of services. If you received accommodations at other educational institutions, but have not yet registered your status with Wayne College, or if you believe you may have a disability and need to get accommodations for it, contact the Disability Services Director Julie Hartzler at (330)684-8923 or, to begin delivery of services.

  7. Integrity   Students are responsible for their academic work. Plagiarism and other forms of cheating or academic dishonesty may result in a failing grade on a test, a failing grade for the course, or possibly suspension from the university.

  8. Harassment   University of Akron is committed to providing an environment free of all forms of discrimination, including sexual violence and sexual harassment. This includes instances of attempted and/or completed sexual assault, domestic and dating violence, gender-based stalking, and sexual harassment. Additional information, resources, support and the University of Akron protocols for responding to sexual violence are available at Students who believe they may have been harassed, threatened or assaulted should contact either Dr. Jane M. Fink at (330)684-8767 or, or Mr. Gordon Holly (330)972-8740
