There was a mistake in the last example in today’ lecture (lecture 16). Here is the correct example.

 Thursday 15th June 2006


I will also be in my office on Monday between 11:00am and 6:00pm. Please feel free to come and ask any questions you may have about the course. Also, if there are enough requests, I can do an additional problem session on Monday, to consist of problems covering this week’s lectures. Please e-mail if you would like me to do a problem session on Monday and also let me know what time you would prefer.
Note that there will be a usual problem session during Thursday’s lecture.

 Wednesday 14th June 2006


I have decided to postpone the handing in of Homework 5 until Friday, 16th June, 5pm; you may still hand it in during the lecture tomorrow, if you prefer. I will be in the office after 11am on Friday and will answer any questions you may have about this week’s lectures or the homework.

 Monday 12th June 2006


Due to illness, the lectures this week will be given by another UBC maths instructor. I will still answer questions by e-mail, so feel free to address any questions to me at the usual address. I will be back next week.

Note that Homework 2 has been modified to make it easier. Namely, in question 3, part a), you have to calculate the curvature, but you dont have to find the point t, which maximized the curvature. Also, in question 3, part b), you no longer have to calculate N. In question 4, part b), v(0)=<1,1,1>. Here is the new version of Homework 2.


Sunday 21st May 2006

Here are  Homework 2 and the solution to Homework 1. Let me know if you find any typos or mistakes in the solution to Homework 1.


Thursday 18th May 2006

Here is  the  derivatives/integrals  formula sheet  you  are  allowed  to  take  to  the  midterms and the final exam .


Saturday 13th May 2006
