 The MATH 102 final exam will be on Monday at 8:30 am  11 am. Information, including links
to old finals and a newly posted (today) collection of practice problems (extracted from quiz problems in all
sections  no solutions included but some solutions are available on the section pages). The old exam links
can be found on the "Final exam information" page and new practice problems are on the "practice problems"
page.

There will be a few study sessions tomorrow (Friday), provided snow does not prevent people from getting to
campus:
 Friday, Dec. 9, 10am1pm in HENN 202.
 Friday, Dec 9, 15 pm in MCML 166
 Friday, Dec 9, 13 pm in BUCH A102

There will be 13 instructors at each of these locations with the exception of 10am11am in HENN 202 (you are
welcome to show up and work in groups during that time and ask questions when the instructor comes at 11).
These sessions will not be lecture style. Student can work in groups on practice exams and posted problems or
any other relevant material. Instructors will circulate and answer questions that come up.
 12.02
 The final exam will be in AMC format. Here is a sample for AMC
format. You can
read the points of each problem from its number of bubbles. Remember to bring a dark pen/pencil to
darken the bubbles!
 Office hours during exam period: 45pm on Tue Dec 6, Thu Dec 8 and Fri Dec 9.
 Review sessions: TBA by email. There are several sessions. The idea is that practice problems
will be distributed
and you work in groups. An instructor or two will be walking around to help.
 You should read the
final exam info page carefully in particular the Final Exam 2015.
Here is a
local copy.

 The final exam will take place on Monday December 12 8:30am11am at MATH
100.
 Many TA hours in MLC have been shifted to the final exam weeks. As a result,
the MLC is open for very limited hours for the next two weeks (see details at the
MLC website. On the other hand, the MLC will stay open
until December 20th.
 You can find old math final exams at Math Department exam
archive. You can also buy exam packages with solutions at UBC Math Club.
 Quiz 3 has average score 6.9 out of max 12. The max is changed from 20 to
12 so that the average 6.9 amounts to 58%. Marks higher than 12 remain
unchanged, so they effectively become
bonus. Here is
quiz 3 solution.
 Comments from our TA for quiz 3:
 The average mark was 6.9/20 which I think was mainly due to trouble with
the last long answer problem, question 7.
As for common problems for the students:
 be careful with using brackets for #1. 2x+1(e^(x^2+x)) is not the same as
(2x+1)(e^(x^2+2))  (2x+1) must be in brackets
 #3 power rule cannot be used for x^(2x)  need to use logarithmic
differentiation
 #4 asks for h(1), not h(x)
 in general, for long answer questions, be more neat/ clear with your work

makes it much easier for the marker and also ensures you wont lose marks
because something is unreadable/ hard to understand
 for #6, be consistent with the use of either dD/dt=kD or dD/dt=kD, it
will
make a difference with the final answer. also, k is a constant, not the time of
half life.
 11.14

 Quiz 3 on Friday Nov 18 will cover the following material (Lecutures 2229, Chapters 1013):
 Exponential functions and their derivatives
 Inverse functions, the log function and its derivative
 Applications using exponential functions
 Qualitative analysis of ODEs (slope fields, phase lines, steady states, stability)
 10.12

 Quiz 2 has average score 11 out of max 20. The drop in average
compared to Quiz 1 is probably due to problem 8. Here is
quiz 2 solution.
 Comments from our TA for quiz 2:

make sure to read the instructions, many people lost marks on #2 for
simplifying when it explicitly tells you not to  for short answer questions
you are only marked on what is in the answer box, not your work.
 even though you arent allowed a calculator, make sure to simplify
numbers,
ex 0.2/0.1=2
 make your work easy to follow and neat on long answer questions  you
can
gain part marks for showing your thinking, but if I cant understand, you
wont get marks for your work
 double check addition, multiplication, etc  many students lost marks
simply because they didnt add correctly on #7
 review the concepts behind #8, a lot of students struggled on this
question. try drawing a graph to see if your answer makes sense!
 The final exam will take place on Monday December 12 at 8:30am.
Location TBA.
 The midterm will cover material from Chapters 16. This includes
everything up to and including "Absolute extrema" but not applied
optimization problems in Chapter 7.
Given the above and that Assignment 6 is all about applied optimization,
the due date for Assignment 6 has be postponed to Tuesday Oct 25 at 7am.
 The Instructor In Charge (IIC) have assigned all students that did not
sign up to a room and time. Please visit the signup form to find out when
and where to go.
 Office hours (OH) before the midterm exam: Thursday 11am (the original

will close on Friday, Oct 7. If you have a
conflict, please report ASAP and you can write at another time.
Legitimate
conflicts include a lecture, a midterm or a religious obligation.
 09.26

 Quiz 1 has average score 15.1 out of max 20. Here is
quiz 1 solution.
 Comments from our TA: The students had the most trouble with the following
questions:
 Q1. many students seemed to either guess the answer, or a common answer
was D)
neither
 Q3. many students either guessed or tried to cancel out terms instead of
taking
the highest power in the numerator and denominator
 Q4b) instead of calculating the time, many students simply halved the value
from
a), the maximal activation level, to try to get the time at which it reaches
half maximal activation level
 Q7. the question was pretty well done overall but a common mistake was
misplacing the limit notation, for example not writing it in before the
expression containing x or continuing to write it even after they had evaluated
the limit.
 09.21

 Quiz 1 will be held in the last 15 minutes of Friday, Septemer 23. It
covers materials from week 1 to the content of WebWork 2. Its format is similar to this

 The
Math Learning Centre (MLC) starts operation today, MondayFriday, 11am

The MLC is a space for undergraduate students to study math together,
with friendly support from tutors, who are graduate and undergraduate
students in the math department.
