Here are the course grades, with final exam scores. The "i" columns are the in-class homework problem scores.
Enjoy the summer!
Grading of the final exams is underway. I will have office hours Friday from 2-4 PM if you would like to come by and see your exam. I hope to have course grades determined by then as well, but I might not.
Here is an example using polar integration in a center of mass calculation (with an animation!).
Professor Kutz in Applied Math would like y'all to know about a study abroad program he is running for next Winter quarter in Rome, Italy. Check it out.
Here is the grade record. 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. Included is also an estimated course grade. This includes the 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.
I mentioned Weierstrass functions in class at some point, and I'd always wanted to make a little zoom-in of one of them so here it is. The animation is at the bottom.
Solutions for the latest midterm are in the exam archive; link at right.
The median in the honors section was 53.
Here is a solution to the recent projectile in-class problem. It's fairly condensed and it needs to be expanded in a few places, but I wanted to get it out to you as quickly as possible.
Although trigonometric identities can be used extensively in this problem, the solution here avoids them as much as possible. There are a couple of "rationalize the denominator" applications which drastically change the appearance of certain expressions.
Let me know if some steps are confusing, or any points are glossed over. I already know a couple: one being the lack of an argument for why this velocity is a minimum. That definitely needs to be added.
Here is a list of topics for the second midterm.
Here is a bit of information about the in-class problem related to symmetry. This treats a bit more than the problem, but the problem's case is included.
I've been thinking about tangent spirals.
Here are some preliminary statistics on the first midterm exam. These are based on two sections of 126D.
| n | 78 |
| min | 11 |
| 1st quartile | 31 |
| median | 42.5 |
| 3rd quartile | 49 |
| max | 60 |
Here are answers to the first midterm exam.
In case you are wondering how to interpret your exam scores, grade-wise, here's a table you can use to get an idea:
| exam score | approx equiv grade |
| 29 | 0.7 |
| 31 | 1.0 |
| 34 | 1.5 |
| 37 | 2.0 |
| 40 | 2.5 |
| 43 | 3.0 |
| 51 | 3.5 |
| 59 | 4.0 |
These numbers are just a guide, and I won't be using them for anything. They are only for illustration.
Here are those parametrically defined curves from today's lecture.
Here are a couple of examples of manipulations of lines and planes you might want to take a look at. At least one may be similar to an example from lecture.
Old exams for studying can be found both at the Math 126 Materials Website and at Dr. Conroy's 126 Exam Archive. My archive only has my exams, but it has solutions. Only last quarter's exam is useful from the archive. The materials website has more exams; exams from Winter and Autumn quarter are useful.
Here is a list of topics for the first midterm. Use it as a starting point in your studying.
Jonathan has changed his Thursday office hours. They are shown at left.
I added a little condition to part 5 of the problem below. This is a statement about the Taylor series based at b=0. Based elsewhere, this would not be true.
Here's a reminder of the in-class assignment from last Friday. Please turn it in this coming Friday separately from the rest of the assigned problems (i.e., the problems in the web schedule). Here's the problem. Five short parts: show each of the following:
The Taylor notes have been updated to include some nice graphics similar to the ones from the first lecture. They are now on a page sandwiched between page 12 and page 13, and are in color. Download them from the link at right and check them out.
Answers to some of the Taylor homework problems are now available at the materials website (link at right).
I modified the homework due Friday to include only the first two problems from the Taylor Homework #2. Enjoy!
The rest will be due next Friday, along with other stuff.
Here are the graphs from today's lecture.
For the first two weeks, we'll be working from the Taylor notes, available here. It can also be purchased at the Communications Copy Center CMU B042. The Taylor notes have five sections, and we'll be covering this material at the rate of approximately one section per lecture, but it might be helpful to read ahead a section.
Welcome to Math 126C, Spring 2006.
This website will be updated with important information and announcements throughout the quarter, so check back often.
