MATH 214-001 -- Elementary Differential Equations -- Fall 2011

Announcements:

Quiz 14. Quiz 14 will be given Thursday, December 8 and will cover Sections 7.1, and 7.3. Remember no calculators are allowed for your quizzes.

Final Exam Review Session. Sam will be running a review session for the final exam on Monday December 12, from 12:30pm to 2:30pm. The location is to be announced. See this space.

Final Exam. As indicated in the syllabus, the Final Exam for this class will be given on Tuesday, December 13, 1:30PM – 4:15PM, in the same room where we have class. No calculators will be allowed for the final, but you may bring three 3x5 cards, or one half-sheet of 8½ x 11, paper with formulas on both sides. The exam problems will be similar to homework problems and those on the midterm exams and on the quizzes. I will supply whatever table of integrals or of Laplace transforms that you need, so you do not need to put anything like this on your notecards.

Approximately one half of the final exam will cover material from the following sections: 2.1-2.4, 2.6, 3.1-3.3, 3.5, 3.6, 4.2-4.4; and approximately one half will cover material from the following sections: 6.2-6.5, 7.1, 7.4-7.6. There will be no problems on the final taken directly from the material in any section not mentioned in the above list. However, it will be assumed that you know the material in the omitted sections to the extent that those techniques are required to solve problems in the named sections.

It will be a very good idea for you to review old homework problems, quiz problems, and midterm exam problems. You can easily devise a practice final exam by taking the versions of the quizzes and midterm exams that you have not already taken, making up a mock final exam, and then taking it under exam conditions.

Exam 2. Exam 2 will be given on Tuesday, November 8 and will cover Sections 3.1-3.6, 4.1-4.4. The exam will take the full class period. No calculators will be allowed on the exam, but you are permitted to bring one 3x5 card with formulas on it (both sides). The exam problems will be similar to homework problems.

Midterm Grades. Your midterm grades have been posted. The grade is computed as follows: (1/3)*(average of first 6 quiz grades, none dropped) + (2/3)*(score on Exam 1). A letter grade was assigned (without + or -) based on the scale given at the end of the syllabus. Since most of our graded work is yet to come, it is likely that this grade will improve as the semester goes on. However, if this grade is surprisingly low to you, you should assess how well you are understanding the material, keeping up with the work, and adequately studying for exams and quizzes. If you would like advice, please come and talk to me.

Exam 1. Exam 1 will be given on Tuesday, September 27 and will cover Sections 1.1-1.3, 2.1-2.4, and 2.6. The exam will take the full class period. No calculators will be allowed on the exam, but you are permitted to bring one 3x5 card with formulas on it (both sides). The exam problems will be similar to homework problems.
