This course is cross-listed as Math 358 and Mech 358.

**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 5th, 2015.
Quiz 1: January 15th
Quiz 2: January 29th
Quiz 3: February 12th
Quiz 4: ~~February 26th (midterm)~~ Re-scheduled to March 3rd (Midterm).
Quiz 5: March 12th
Quiz 6: March 26th
Final exam: **April 17, 2015 03:30PM in Osborne A**.

### 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%. Labs: 35% total. Regular quizzes: 25%. Midterm quiz: 10%.
Quizzes are scheduled for class time on the following dates: January 15th, January 29th, February 12th, February 26th, March 12th, March 26th. The quiz on February 26th will constitute the midterm for the class and is worth more marks.
Missing a quiz or 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 quizzes or midterms will be given.
Homework assignments will be handed out approximately every two weeks.
These will contain problems that you should work and understand before
completing the computer labs, quizzes and midterms. Most assignments will not be collected or graded so you will need to review the solutions yourself.
The computer labs should be completed in pairs except as discussed in advance with the instructor. You are welcome (even encouraged) to discuss the labs in larger groups, but each pair must submit **only** their own solutions. UBC policies on cheating and plagiarism are extremely strict.
If in doubt, enquire before submitting.
**Note:** You will have *immense* difficulty with the quizzes, exams and the
course if you don't understand the labs and homework.

### 2014 Final Exam Information

Final list of topics for the 2014 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".
