Here is the updated grade record, with final exam scores and course grades. These are your actual course grades that I will be reporting to the registrar (so they include the curve, dropped lowest homework score, etc.). If you notice any errors in the record, please report them to me.
I will be in my office on Friday from 1 to 2 pm if you would like to see your final exam or talk about any grading questions. You are also welcome to stop by any time next quarter.
Have a good break!
Here are the stats for the final exam: n=46, min=17, 1st quartile=58, median=67, third quartile=89.25, max=100 (2 people).
Grading of the final exams is going swiftly. I expect to have the grade record updated here by Thursday evening. I also intend to have an office hour on Friday,from 1 to 2 PM, in Padelford C-544, if you wish to see your final exam. At the moment, I have a nasty head cold (or something), so there is a possibility I will cancel this office hour: just check here on Friday morning to see if I've added a cancellation message.
If I don't see you Friday, you can always stop by during my office hours next quarter to see your final exam. My hours will be listed here after the start of Winter quarter.
Have a good break!
The homework schedule has been updated with problem for the last two sections, 4.5 and 4.7. These won't be collected, but they are good practice for the final exam.
Look at the discussion board (link at right) for suggestions for studying for the final exam and for links to old final exams.
Here are two applets to help you think about what we are doing in these optimization problems (like those in section 4.7).
This one illustrates the classic rectangular enclosure problem(s), like 5, 7, and 9 from section 4.7.
This one illustrates the problem of making a Norman window (see problem 28 from 4.7).
Here is a review sheet, or course summary, to help you prepare for the final exam.
Here is the grade record. Please check it right away to make sure your scores are recorded correctly.
Your grade information is listed under the last four digits of your student id number. Be sure to check that your scores have been recorded correctly. If you find an error, please bring it to the attention of your TA right away. Included is also an estimated course grade. This includes the course curve, and the dropping of your lowest homework score. Obviously it does not include the final exam: that can have a very large impact on your actual course grade.
Answers to the second midterm are here.
Here are some statistics for the second midterm:
| n | 47 |
| 1st quartile | 47 |
| median | 58 |
| 3rd quartile | 65 |
| maximum | 70 (4 people) |
Please print this worksheet and bring it to section tomorrow. Thanks.
CLUE is holding a review session for Math 124 tonight at 6:30 in Mary Gates Hall, MGH 241.
Here is a review sheet for the second midterm.
Here is the related rates handout from Monday's and Wednesday's lectures.
Please print this worksheet for Tuesday's quiz section (you already haveit if you have the coursepack).
Here are some statistics for the first midterm:
| n | 48 |
| 1st quartile | 43.75 |
| median | 53 |
| 3rd quartile | 59 |
| max | 65 (4 people) |
There were a lot of good scores on this exam. As a guide to how your score would translate to a grade, I give you this table:
| ≤26 | 0.0 |
| 27 | 0.7 |
| 30 | 1.0 |
| 35 | 1.4 |
| 40 | 1.9 |
| 45 | 2.3 |
| 50 | 2.7 |
| 55 | 3.2 |
| 60 | 3.6 |
| 65 | 4.0 |
These are approximate grades, and I don't use this translation for
anything: this is just to give you an idea of how the curve works.
If I had to give a grade today, based just on the exam, this is approximately
the way I would assign grades. In reality, I don't apply any curve
until the end of the course, and I have combined all scores into
a composite score for each student. Then I apply a curve to that.
Answers to the first midterm are now on the "old exam" archive, linked at right.
Here is the worksheet for this Tuesday. Please print it and bring it to section.
CLUE will be holding a review session for Math 124 on Monday, October 22 from 6:30 to 8:00pm in Mary Gates Hall 241.

I'm holding extra office hours this week to facilitate the required office visitations. Here are my office hours this week, all in my office Padelford C-544:
| Monday | 10:30-12:15 |
| Tuesday | 2:30-3:30 |
| Wednesday | 10:30-12:15 |
| Thursday | 2:00-3:00 |
| Friday | 10:30-12:15, and 3:30-? (to whenever there is not a stream of students at my office door) |
Check this page for help in finding my office.
Please bring this worksheet to quiz section Tuesday, October 9. It is in the course pack, or you can print it.
Speaking of parametric equations, you might like to have a look at the web page for a seminar I ran last spring. On the right of this page are a bunch of links to applets I wrote to demonstrate a variety of curves, many of which are defined parametrically.
Fun stuff, I think.
For some help with one of this week's homework problems, take a look at this. Note the speed is not the same as in the homework problem.
In this week's homework assignment, there are references to a coupld of "web supplements". These are available on the 124 Materials Website, and may be helpful in solving the homework problems. Here are some direct links:
The worksheet for next Tuesday is here. It is also included in the course pack. Please bring a copy of the worksheet to quiz section.
