Office hours: Monday 2:00-3:30 PM, Thursday 10:30-12:00 AM.
Office hours room: Leonard S. Klinck building, LSK300B/LSK300C.
Uncollected homework/midterms are placed in front of my office, and can be picked up there anytime the hall door is unlocked, which is usually the case between 10AM and 6PM.
Final exam date: December 15, 3:30 PM.
Final exam location: SRC A.
Final exam conflicts/hardships:
If a student has an exam conflict or hardship, he should contact me by email as soon as possible so that an arrangement may be found with the math department. An exam hardship is defined as three exams within 24 hours, and an exam conflict can be two exams at the same time, a religious holiday, or another serious problem.
Content of the final exam:
[Lebl's textbook and the complementary draft chapter]
Chapter 1 except § 1.5
Chapter 2 except § 2.3
Chapter 6 except § 6.2.4, 6.3.3, 6.4.4
Chapter 3 except § 3.6.1, 3.8, 3.9.1, 3.9.3 but including the method of undetermined coefficients in § 3.9.1
Chapter 8 (the draft one) except § 8.2.3, 8.4, 8.5.
Recommended preparation for the final exam:
To learn or relearn the course material, the students are encouraged to read or at least check the examinable content in Lebl's book, and to consult the complementary sources (see "References"), which cover many topics from the course, but not all of them and not always in the same fashion. The book by Boyce and di Prima is a classic, but is slightly too exhaustive for this course. The book by Logan is excellent, but a bit difficult for this course. The sections from these books which are relevant to this course are listed below (many of them contain non-examinable material: consider them as optional secondary sources of information).
[Boyce and di Prima]
1.1, 1.2, 1.3
2.1, 2.2, 2.3, 2.6, 2.7
3.1, 3.2, 3.3, 3.5, 3.6, 3.7, 3.8
6.1, 6.2, 6.3, 6.5, 6.6
7.1, 7.2, 7.4, 7.5, 7.6, 7.8, 7.9
9.1, 9.2, 9.3
1.1, 1.2, 1.3, 1.5, 1.6, 1.8
3.2, 3.3, 3.4.4, 3.7
4.1, 4.2, 4.3, 4.4, 4.5
6.2, 6.3, 6.5
To prepare for the final exam, the students are also encouraged to try the practice midterm and final exams, to try again the homework assignements and to do exercises from the official or complementary textbooks.
