**Text of final exam, spring 2015**

final grade = w1*homework + w2*midterm + w3*final

subject to constraints 0.1 ≤ w1 ≤ 0.3, 0.1 ≤ w2 ≤ 0.25, 0.5 ≤ w3 ≤ 0.8 with w1+w2+w3=1.

In other words, the final is worth at least 50% and at most 80%; homework are worth at least 10% and most 30%, and the midterm is worth at least 10% and at most 25%.

** Homeworks/handouts**

** Textbook**
The textbook for this course is Elementary differential equations with
boundary value problems, by C.H.
Edwards and D.E. Penney. It is available in Dalhousie bookstore; a copy
is also on reserve in the Math Learning Center, room Chase 119. By the
way, that room is also a good place to study. It is staffed by TA's who
can (try to) answer your questions.

** Outline: **
We will cover chapters 5,3,6,7,8,9. Additional material not on the book
may be used especially on dynamical systems (chap 7) and PDE's (chap 8).
I will provide additional references/notes in this case.

**Grade conversion scale scale: **
[0-50) F, [50-55) D, [55-58) C-, [58-62)

**Intellectual Honesty and Plagiarism: ** If you cheat, you will
get into lots of trouble. Suspected cases of cheating will be referred to
the Faculty Academic Integrity Officer. Punishments can include a
suspension from university for a year! It is not worth it. For details,
please read the section on academic honesty in the student calendar.
