Grades are now available on Catalyst. These are the actual grades I will be reporting to the registrar. They include the curve, and each student's lowest homework score was dropped in the calculation of each student's homework average; all of your scores appear as a matter of record.
Have a good break!
Final exam stats: n=322; min=5; 1st quartile=46; median=58.5; 3rd quartile=68.75; max=80 (5 students)
I will have an office hour this Friday, 1-2 PM, if you would like to see your final exam. I expect to have grades calculated by then as well.
If you cannot make that time, you are welcome to stop by during any of my office hours next quarter.
Enjoy the break!
CLUE will be holding a review for Math 120 on Friday, December 10, from 7:15 to 9:15 PM in Mary Gates Hall.
The MSC will be open this Friday until 9:30 PM and then will close for the quarter.
Here is a review sheet for the upcoming final exam.
Answers to the second midterm are available here.
Stats on the second midterm:
120 B: n=182; min=6; 1st quartile=16.25; median=23; 3rd quartile=28; max=38.
120 C: n=147; min=7; 1st quartile=20; median=26; 3rd quartile=31; max=40 (one student).
For both exam 1 and exam 2, different exams were given to the B and C sections. Grades for these sections will be calculated independently; current grade estimates on Catalyst were calculated independently.
This week, we will be talking about sinusoidal functions, which are dilated, shifted version of sin x. Here is an applet illustrating these kinds of functions.
You might like to know that the MSC will be closed this Wednesday through Sunday.
When using the exam archive, you need to be aware that not all problems on all second midterms are relevant. Here are some suggestions of good problems to use for practice.
A review sheet for midterm two has been added to the Handouts and Supplements, at right.
Also, I have been informed that CLUE will be holding a review for Math 120 on Wednesday, November 17. The session will be held in MGH 295 from 7 to 9 pm.
Hey folks, the Flatiron Building was mentioned in one of the lectures today. According to Wikipedia, its pointy angle is about 25 degrees. It's one of the icons of New York City.
Answers to the first midterm exam are now available on the 120 Materials Website, here.
Here are some statistics for the first midterm:
n=341; min=2; 1st quartile=18; median=25; 3rd quartile=31; max=40 (8 students)
Here is a table showing approximately how a score on the exam might translate to a 4.0 scale. This is just to give you a sense of how you are doing; I only apply a translation of this sort at the end of the course.
| exam score | approximate 4.0-scaled grade |
| <17 | 0.0 |
| 17 | 0.8 |
| 18 | 1.1 |
| 19 | 1.4 |
| 20 | 1.6 |
| 21 | 1.8 |
| 22 | 2.1 |
| 23 | 2.3 |
| 24 | 2.6 |
| 25 | 2.8 |
| 26 | 2.9 |
| 27 | 3.0 |
| 28 | 3.1 |
| 29 | 3.2 |
| 30 | 3.2 |
| 31 | 3.3 |
| 32 | 3.4 |
| 33 | 3.5 |
| 34 | 3.6 |
| 35 | 3.7 |
| 36 | 3.8 |
| 37 | 3.9 |
| >37 | 4.0 |
Review tonight at CLUE, 7-9 PM in Mary Gates Hall. I don't know the room number: I imagine there will be signage.
In case you'd like to get an idea of what exams in this course are like, take a look at the 120 Materials Website (link at right). There, you will see a link to the Test Archive which has many, many old exams from this course. You may as well focus on my exams (all the links labeled Conroy are links to my exams). Check out the Midterm #1 exams for ones relevant to the upcoming exam.
I've added a handout on the technique of completing the square to the right hand column of this site. You will need this technique in problem 3.2.
Welcome to Math 120 B & C, Autumn quarter 2010.
Announcements and other useful things will be posted here during the quarter, so check this site frequently.
Textbook: The textbook for this course is Precalculus, by Collingwood and Prince, the 2010-11 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. The price is $24.99 plus tax.
You do not have to purchase the textbook. It is available electronically on the Math 120 Materials Website (link at right).
It is necessary that you use the 2009-10 edition. Many changes were made from the 2008-9 to the 2009-10 edition, and there will be much confusion if you try to use the 2008-9 or earlier editions.
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 Schedule: The homework schedule is available at right. This is the only place this information is available, so please check here to get the schedule.
