Here is the grade record, with final exam scores and course grades. These are the actual course grades, including the course curve.
Here are the final exam stats: min=4, 1st quartile=47, median=59, 3rd quartile=72, max=98.
Have a good break!
I'm almost finished grading the final exam - I should have grades posted by the end of the week. Unfortunately, I won't be able to hold office hours this week. If you'd like your final exam, you can stop by office hours after the start of next quarter.
Here is a course summary or review.
Here is the current grade file. 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.
Here are answers to the second midterm.
Here are some stats on the second midterm:
| n | 68 |
| min | 13 |
| 1st quartile | 35 |
| median | 42 |
| 3rd quartile | 48.25 |
| max | 60 |
I'll post a grade record this week that will include an estimate current course grade for everyone.
Answers to the exam will be posted later on Tuesday.
Here is a review sheet for the second midterm.
Old exams can now be found at the link in the column on the right under Resources.
We'll be going over Midterm 2 from Spring 2005 on Friday.
Problem 6 of week 5 is quite challenging, so I've written a similar example to show you a good method for solving problems like this.
Here it is.
Here are the first exam statistics:
| n | 71 |
| min | 37 |
| 1st quartile | 57 |
| median | 61 |
| 3rd quartile | 66 |
| max | 76 (4 people) |
| ≤42 | 0.0 |
| 43 | 0.7 |
| 45 | 1.0 |
| 50 | 1.6 |
| 55 | 2.2 |
| 60 | 2.9 |
| 65 | 3.3 |
| 70 | 3.6 |
| 75 | 3.9 |
| 76 | 4.0 |
Here are the answers to the first midterm.
Here is a graphic illustrating the curve in problem 3.5 #48. This is actually the top half of the complete bullet nose curve, which has equation y2(2-x2)=x2.
Here is an animation illustrating the slope of the tangent line to bx at x=0 for various values of b. This can be taken as the definition of e: it's the value of b such that the slope of the tangent line at 0 is 1. (reload if the animation won't go)
Here is the most recent midterm one that I've given in Math 124, from Spring 2005.
Here are answers for that exam.
Here is another old exam of mine, from Winter 2003.
Here are solutions for that exam.
Problem 6 from week 3, the "wolves and caribou" problem is pretty challenging, so I wrote up a page of hints and discussion on it. Stop by during office hours if you want to talk about it.
I removed the 2.5 material (i.e. part 1 of week 3) from this week's homework assignment. I'll be moving it to next week's assignment.
Here is an animation illustrating a problem of continuity involving a piecewise-defined (i.e., multipart) function with a parameter. There will be an example in lecture on Friday that is similar.
I removed part 6 of the "Week 3" assignment from this week's homework; it'll be due next week. It relies on the idea of infinite limits which we'll discuss Friday.
Here is a little discussion on the curious functions sin(1/x) and x sin(1/x).
IMPORTANT ANNOUNCEMENT!! I have decided to change the date of the first midterm exam, to allow us to cover more material before the exam. The first midterm exam will be on January 30. That is,
Midterm One is on January 30
instead of January 23. Please make a note of this! Please help spread the word!
You will need to bring a copy of this week's worksheet with you to quiz section on Tuesday. This is included in the course pack, or you can print it from the Materials Website. Follow the link at right to the 124 Materials Website, then click on Outline 2 (for week 2), then click on the link for the Worksheet. The worksheets are in pdf format.
The homework schedule is now available. Use the link at right.
Additional readings can be found on the 124 Materials Website. Click on the link at right, then on the "Outline" link for the appropriate week's supplemental material.
Welcome to Math 124 I, Winter Quarter 2007.
