Special question and answer session Friday Dec 12 from 11-1 in Math Annex 1100.
Will also be around Thursday and Friday at various times for questions. Let me encourage you to come around Friday Dec 5 11-12 (the assignment 8 will be on a chair outside my desk in alphabetical order) and say Thursday Dec 11 11-12.
Assignment 8 solutions posted. Test 4 solutions posted. Assignment 7 solutions posted.
You can visit the 104/184 course website to see old exams 2004 and 2006, the latter having many short answer questions at the beginning of the test. You could visit the math club (MATH ANNEX 1119) this week to purchase the two exams and solutions. You could also use MATH 100/180 exams for some practice problems.
Solutions to test 4 posted.
Solutions to test 3 posted. Average was 64 median 66. Good work!
Solutions to test 2 posted. The test organization went well but it seemed to be a little long. Average was 48. I am recording grades as if out of 80 and so average is `60'.
Solutions to test 1 posted. The test was a little too easy apparently because the algebra was not challenging enough. The average was 68. Grades from 80 to 100 are probably 10 markes too high.
All last years tests have been posted for study. Be warned that the order of material was different last year.
Second Basic Skills test Monday Sept 22 evening. Those who scored less than 20 on first test (about 1/3 of class) must write second test and of course we encourage more review of basics. Sign up now for space.
Workshops working well but first workshop ended up a little too easy. Many students manipulated logs correctly. Good work! Second workshop should be harder.
Lectures 12:00-1:00 MWF in MATH 100 plus 1.5 hour workshop either Tuesday 11:00-12:30 (Sec 101 in MATH 103,Sec 102 in MATH 225, Sec 103 in MATH 204, Sec 104 in MATH 105) or or Thursday 11:00-12:30 (Sec 105 in MATH 103, Sec 106 in MATH 225, Sec 107 in MATH 204, Sec 108 in MATH 105).
Welcome to UBC. Most of you are first time university students and so life will be hectic for you as you adapt to university life. This course will need you attention early and often. There are no workshops the first week and they begin the second week. Experience has shown that the workshops are enjoyed by students and they benefit from the learning experience. The workshops are not a replacement for homework but will hopefully equip you with the tools to study more effectively. Attendance/particpation in the workshops will count 10% of your term grade (5% of your final grade).
You (and all students in MATH 184) will have a Basic Skills test on Monday September 8 either 6:00-7:30 pm or 7:00-8:30pm
and an additional test Monday September 22 again either 6:00-7:30 pm or 7:00-8:30pm.
Details about skills test including signup . You will be required to write the second test if your initial grade is
less than 20/30. The test counts 10% of your term grade (5% of your final grade).
I will have an early midterm.
You may feel that you are in the wrong course. You may wish to transfer to a course with more emphasis on the basic algebra such as MATH 110 (6 credits) or Continuing Education non credit course 001 or 003. You may feel your background is good enough that you do not need the workshop and then you take MATH 104 a 3 credit course or if you are highly able in Mathematics you could consider the honours course MATH 120, a 4 credit course. I can provide advice and your results in skills test or term tests may help you decide. Most of you are in the right course; don't worry.
I arrive most days by 9:00.
I typically do not read my email from home (i.e. evenings and weekends).

I am posting my last years tests. Note that I followed a different order of material. Test 4 is more relevant for our test 2. Test 3 is more relevant for our test 3.
Test 1 given last year.
Test 2 given last year.
Test 3 given last year.
Test 4 given last year.
I will NOT post solutions. The idea of a sample test is to give you a chance to see the format and try out your skills on new problems. You can read worked problems eleswehere. The text is helpful. I will have some special office hour just before the midterms perhaps Wednesday 3-4 and 4-5 and Thursdays 3-4. Check for room information.
Test 1 solutions. No grading complaints after Oct 3 class.
Test 2 solutions. No grading complaints after Oct 20 class.
Test 3 solutions. No grading complaints after Nov 17 class.
Test 4 solutions. No grading complaints after Nov 28 class.

Harder problems. Some more difficult problems for you to try.
A justification for the chain rule and product rule using the idea that functions (that are differentiable) can be approximated by linear function.
Notes on Inverse Trig functions We use the same ideas of inverse functions that were used to compute the derivatine of ln x fron the derivative of exp(x). Finding an inverse involves domain issues much s for the function x squared.
