Hi folks!
Grading of the final exams has commenced.
I will be holding one office hour this week, on Friday, December 14, from 2 to 3 PM so you can stop by if you would like to see your exam.
If you can't make that time, you are welcome to stop by any of my office hours to see your exam next quarter. My office hours will be posted on my math department page when I decide what they will be.
I will post final exam scores to Catalyst, along with grades, when I have calculated course grades. I hope to have done this by Friday at 2, but it may take longer.
Thank you all for an enjoyable quarter. I don't remember when I've had such a hard-working, enthusiastic group of students.
Have a good break!
Dr. ConroyCLUE will be holding a Math 120 review tonight from 5 to 7 pm in MGH 389 (our regular lecture room).
Here is a review sheet for the final exam.
Answers to the second midterm exam are now in the Math 120 Exam Archive (at the 120 Materials Website).
Here is the bicycle example from Monday's lecture.
Statistics for the second midterm exam: n=283; min=0; 1st quartile=20; median=29; 3rd quartile=33; max=40 (1 student)
CLUE will be holding a review session, Wednesday 11/14, from 8 to 10 PM, in MGH 389.
When studying for the second midterm, you must exercise care using the exam archive. Many problem on the midterm 2's in the archive are not relevant to you at this point in the quarter. All problems involving angular calculations or rotational or circular motion should be skipped. This includes anything with the word "sinusoidal" and anything mentioning a circular track.
Here are some relevant problems from my midterm 2's in the archive.
Winter 2012 - problems 1,2,3
Autumn 2011 - all
Spring 2011 - 1, 2, 3
Winter 2011 - 1, 3, 4
Autumn 2010 - B: 1, 3, 4; C: all
Winter 2010 - all
Autumn 2009 - all
Spring 2009 - problem 1
Winter 2009 - 1, 2
Autumn 2008 - 1, 2
Spring 2008 - problem 1
Other exams can be looked at for linear-to-linear rational function, quadratic optimization, function composition and inverse and other types of problems relevant to this exam.
Here is a review sheet for midterm 2.
Answers to the first midterm are now on the 120 Materials Website.
Statistics on the first midterm: n=311; min=1; 1st quartile=16; median=24; 3rd quartile=31; max=40 (6 students)
Here is table giving an approximate 4.0-scale interpretation of your exam score. This is just to give you a rough idea of how you are doing. The curve used to create this interpretation will not be the same curve used at the end of the course to determine your grade, since that curve will involve more data, but it will be somewhat similar.
| ≤16 | 0.0 |
| 17 | 0.7 |
| 18 | 1.0 |
| 19 | 1.3 |
| 20 | 1.6 |
| 21 | 1.9 |
| 22 | 2.2 |
| 23 | 2.5 |
| 24 | 2.8 |
| 25 | 2.8 |
| 26 | 2.9 |
| 27 | 3.0 |
| 28 | 3.1 |

CLUE will be holding a Math 120 review session on Wednesday, 10/17, from 8 PM to 10 PM, in MGH 241.
I added a handout which shows how to find a quadratic function given three points on its graph. This example is a little more general than the example done in class.
Here is a review sheet for the first midterm exam.
CLUE will be holding a review for the first midterm, but it has not been scheduled yet. I will update this page when I know when it will be held.
I added a link to a handout on domain and range that should help with at least one of the homework problems.
I have added a link to a handout on similar triangles to the the right column of this page. You will want to use the similar triangles idea on some problems in this course, particularly those related to bungee cords.
Welcome to Math 120 A, B Autumn quarter 2012.
Announcements and other useful things will be posted here during the quarter.
Textbook: The textbook for this course is Precalculus, by Collingwood, Prince and Conroy. We will use the 2012-13 edition (this is the latest edition). The book can be purchased at Professional Copy and Print, located at 4200 University Way (on the Ave one block south of the UW bookstore). It is not available at the UW bookstore.
You do not have to purchase the textbook. It is available electronically on the Math 120 Materials Website (link at right), and is linked electronically from the WebAssign homework.
Discussion Board: The course has a discussion board (link at right). This is a great way to ask questions of me in a way that will benefit all students in the course. You can ask about homework questions, studying methods, etc. You can also use it to coordinate study sessions with other students.
Homework: We will be using WebAssign for homework.
WebAssign: You can log in to WebAssign here. This will require your UW Net ID. Your UW Net ID is the part of your university email address before the @ symbol. The password to log in is your UW Net ID password.
You will need to purchase an access code before the grace period ends. You can purchase an access code on the WebAssign website after logging in.
The first homework assignment will be due on the night of Thursday, October 4.
