Text: There is no required textbook for the course, but the following are recommended.
  • Elementary Differential Equations and Boundary Value Problems (10th ed.) by W.E. Boyce & R.C. DiPrima.
  • The online textbook Diffy Qs by J. Lebl. You can download the book (for free) or order a copy (for cheap) to be sent to you from this page: http://www.jirka.org/diffyqs.
  • Applied Partial Differential Equations (with Fourier Series and Boundary Value Problems) (4th ed.) by Richard Haberman
  • Any of the zillion books with titles like "Differential Equations with Matlab". One such book is Applied Numerical Methods with Matlab (2nd ed.) by Steven Chapra

    Important Dates:

  • First class: 11am, January 6th, 2014.
  • Midterm: Thursday, March 5th
  • Final exam: Monday, April 14th, 3.30pm

    Subject matter:

    The study of analytical and numerical solutions of ordinary and partial differential equations, with emphasis on those arising in Mechanical Engineering applications. Prerequisites are multivariable calculus including partial differentiation and integration; linear algebra and matrix theory; a first course in ordinary differential equations; and elementary numerical analysis.

    Grading

  • The breakdown of marks between course elements will be as follows: Final exam: 30%. Midterms: 20% each. Labs: 20% total. Homework: 10% total.
  • Missing a midterm normally results in a mark of 0. Exceptions may be granted in two cases: prior consent of the instructor or a medical emergency. In the latter case, the instructor must be notified within 48 hours of the missed test, and presented with a doctor's note immediately upon the student's return to UBC. No make-up midterms will be given.
  • Assignments will be handed out approximately every two weeks. These will contain problems that you should work and understand before completing the computer labs. Collaboration is allowed on homework assignments, with the usual warning that you should be sure you understand the material even if you collaborate and you must hand in only your own work. The computer labs should be done independently. Note: You will have difficulty passing the exams and the course if you don't understand the labs.
  • You have to submit only your own computer labs and homework. Although you are welcome to study together and discuss the homework with other students, the work you submit (electronically or on paper) must be your own. UBC policies on cheating and plagiarism are extremely strict. If in doubt, enquire before submitting.

    Homework assignments

    Final

  • Final list of topics for the exam.
  • The math department offers the course Math 257/316 which is reasonably close to this course. You can find a range of past exams for that course, many of which have solutions available. You can safely ignore any question from that course that involves the words "singular point", "Bessel function" or "Frobenius".
  • Math dept past final exams
  • Math Exam and Education Resources wiki
  • MATH 257 collection maintained by UBC's Engineering Physics Student Association.
  • There are a few solved past final exams on Professor Peirce's MATH 257/316 pages.
  • The UBC Math Club has packets of past final exams with solutions for sale in the Math Annex. Math Club website.
  • Don't forget the Math Learning Centre in rooms 300–302 of the L. S. Klinck building.
  • The final exam will contain the same formula sheet as Midterm 2. The final exam will contain this formula sheet.
  • Here are the final exam and midterm two from last year. Last year's final; Last year's midterm. The style is different than this year because they have an open-book section and a closed-book section. We will just have a closed-book exam. However, the problems are all relevant to this course.
