  • 15 Apr: there is a minor error in the exam on 16 April which I hope to draw your attention to:

  • 10 Apr: please submit your project reports at this link:
  • 03 Apr: some practice questions for the final exam are being added to the document below. Treat this as a final (ungraded) assignment, since it contains questions on the materials recently covered in class.

  • 02 Apr: you should be aware that the project due date has been extended to 13 April at 16:00. This should fit in with the lighter exam load that most of you have.

  • 17 Mar: we are scheduling small group meetings with myself in the tutorial location on Friday and Monday and then some slots are available on Wednesday (in my office). Please select your slot here (first-come, first served):
Details about what will be discussed in the 10 minute meeting will be described in class on Wednesday.
Please note, as mention in the project outline, the project meeting is graded (and therefore not optional).
  • 16 Mar: the midterms were returned in class on Monday. The solution is also posted. The grade is out of 94 marks. I forgot to mention in class that the following is now on Avenue:
  • the grade breakdown for each question
  • your individual percentage (add up the 5 marks and divide by 94 to get a percentage)
  • the collaborative percentage
  • the overall percentage = max(your grade, or 85% your grade + 15% collaborative grade). So the collaboration will never decrease your individual grade.
  • Question 5 has been updated now with the non-zero grade
  • 15 Mar: Please also bring your printed copy of handout 09A to class; we will continue with those notes from last week.
  • 11 Mar: as mentioned in a prior class, we have a guest speaker today. Here are the notes for her lecture: guest lecture slides. Feel free to print a copy for yourself to take notes on.
  • 06 Mar: the next assignment is posted. As requested in the class evaluations, the assignments are shorter, focus more on hand-calculations, and formulating problems. It is due on 12 March.
Please note that question 1 was modified slightly on Sunday, 08 March.
  • 04 Mar: the date for the final exam is posted now, Thursday, 16 Apr at 19:00.

  • 24 Feb: the collaborative test in class on Wednesday will review important concepts from the written midterm, and extend your knowledge. It won't be a regular repeat of the midterm - there are some important extensions. Don't miss this one. Please come early/on time, since you only have the class time to write and finish it.
