Here are the course grades, with final exam scores.
Enjoy the summer!
Final exam stats, out of 100: min=11, 1st quartile = 49, median = 64, 3rd quartile = 74.5, max=98.
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.
Preliminary statistics: n=71,min=21,1st quartile=38,median=46,3rd quartile=54,max=60.
I'll be posting a grade record later this week, so that you can check that all scores have been recorded correctly, and there will be a current estimated course grade, that includes both exams.
Here is a list of topics for the second midterm.
I've been thinking about tangent spirals.
Here are answers to the first midterm exam.
Here are some preliminary statistics on the first midterm exam.
| n | 78 |
| min | 11 |
| 1st quartile | 31 |
| median | 42.5 |
| 3rd quartile | 49 |
| max | 60 |
Here is a very rough translation scale. This is only approximate and is here only to give you an idea what your grade in the course would be based solely on this exam. I don't use these numbers for anything: they are only for illustrative purposes.
| 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 |
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.
Someone asked me what the equation would be for the surface defined as the cylinder consisting of all lines through the unit circle in the xy-plane, parallel to the line z=y=x. If we imagine the trace of this surface at any value of z (i.e., slice through the surface with a plane parallel to the xy-plane), we have a circle with center (z,z,z). This circle has equation (x-z)2+(y-z)2=1. Since every point on the surface is part of some trace, this equation must be satisfied by every point on the surface. So that is the equation of the surface. Note that it can be expanded to x2+y2+2z2-2xz-2yz=1. These terms involving more than one variable are part of the messiness you get with cylinders whose axes are not parallel to the coordinate axes.
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.
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 126D, Spring 2006.
This website will be updated with important information and announcements throughout the quarter, so check back often.
