I reserved MATX 1118 on Tuesday December 13th from 10:00 to 13:00 for office hours before the exam.

Today’s office hours will be from 12:30 to 13:30 only (in the usual place).

Quiz 5 is now in the MLC for your pick-up.

The common mistakes were:

• Question 1: many of you messed up the revenue.
•  Question 2:  some of you forgot that in the last coefficient you should divide the derivative by 2.

Here are the solutions to the midterm.quiz5a quiz5b quiz5c

Add your suggestions as a reply.

First of all, for some reason quiz 3 didn’t arrive to the MLC. Today I made sure that it got there so you can pick it up. Quiz 4 is also there waiting for you.

As for common mistakes in quiz 4, there weren’t that many apart for calculation errors. In question 3 some people mistakenly compared the elasticity to 0 instead of -1 and in question 4 forgot that x=0 is also a critical point.

Here are the solutions for quiz 4: quiz4a quiz4b quiz4c

Use your time well to study for the midterm. It is going to be on Thursday November 17th on 6:45-7:45 at the same place as the first midterm, that is Buchanan A203. Please make sure that you bring your student card to the test and pleas arrive to the right place (I’m going to be there!).

I would also like to remind you of the various resources you can use when studying for the midterm:

1. Office hours (Tue 12:30-14:00 and Thu 13:00-14:30 at MATX 1118)
2. The MLC is a great place to sit and study with the extra benefit of having TAs willing to help you.
3. Searchable exam database and past exams (which contains more exams but is not searchable by topic)
4. CLP problem book

Tomorrow (Tuesday November 7th) I will have to leave early so office hours will end at 13:30.

No office hours tomorrow.

Hi,

Quiz 3 is in the MLC, don’t forget to bring your UBC card.

Her are the common mistakes you made in the quiz:

1. Not a mistake per se, but some tried to log both sides of the equation before deriving and ended up with a more complicated exercise.
2. Some of you confused dy/dz with dz/dy. Remember, dy/dz means deriving y(z), i.e. y as a function of z.
3. Most of you got this right but didn’t write your answer clearly.
4. Most of you confused this one or didn’t explain yourself at all. Please look at the solutions.

Today’s office will have to be shorter again.

They will be 12:30-13:30 in the usual place.
