Final Exam:
December 9, 1:30-4:20 PM
Location: Sieg 134
Here are the policies for the final exam.
Here is the grade record. This includes the final exam scores and course grades. These are the course grades I will be giving to the registrar, and include the course curve and the dropping of your lowest homework scores.
Please drop by my office hours after the start of winter quarter if you would like to see or have your final exam.
Have a good break!
Final exam stats:
| n | 77 | min | 26 |
| 1st quartile | 57 |
| median | 70 |
| 3rd quartile | 82 |
| max | 98 |
Grading continues. I hope to have grades posted late Friday, but I won't be able to have office hours before break for you to pick up your exams. Please drop by after the start of winter quarter if you would like your final exam. I will be posting final exam scores to the grade record when I post course grades.
Here is a gallery of some of those orthogonal trajectory images from today's lecture. Enjoy!
Here is the current 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 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 some statistics for the second midterm:
| n | 79 |
| 1st quartile | 27 |
| median | 34 |
| 3rd quartile | 43 |
| max | 52 (out of 55) |
I'll post a grade record later this week which will include a current estimated grade, including both exams and the course curve.
The answers for midterm 2 are now available. Follow the "old exams" link on the right.
Here is a review sheet for the second midterm.
The big thing, clearly, for the second midterm is integration techniques. You should be practicing lots and lots of integrals. Here are some places to get practice:
On the exam, you need to show work for all integrals not listed in the table of basic integrals on page 506 of the text. Feel free to put others on your notesheet, to check your work, but work will need to be shown for full credit.
Here is a handout with more integrals to practice, and some advice. Here are some hints and solutions.
Note that integrals 18, 27, and 31 involve the third case of the partial fractions method, which won't appear on the second midterm or the final.
Here are some hints for the donut problem.
For the orthogonal functions problem, you need to use integration by parts twice, resulting in an equation like I=(M/N)2I where I is the integral from 0 to 2 pi of sin(Mx)sin(Nx). If M and N are not equal, what can you conclude the value of I must be?
Here are some statistics for the first midterm:
| n | 80 |
| min | 15 |
| median | 57 |
| max | 75 (2 people) |
Here is a rough grade translation table. I don't use this translation for anything: this is just to give you an idea what your grade might be if all it was based on was the first midterm:
| <40 | 0.0 |
| 40 | 0.7 |
| 45 | 1.4 |
| 50 | 2.1 |
| 55 | 2.9 |
| 60 | 3.2 |
| 65 | 3.5 |
| 70 | 3.8 |
| ≥73 | 4.0 |
Answers to the first midterm can be found on my old exam page.
Ooops! I made a little error in the calculation of the work to remove the dirt from the 8 m deep, 6 m wide conical hole. Assuming a density of 1400 km/m3, the work needed is 2068927.257948094 J = 574.702016 watt hours.
Here's a review sheet for midterm 1.
Here's the deal with the course pack. All the information in the course pack can be found via the 125 Materials Website. You do not need to buy the course pack, provided you are willing to print the worksheets and any other materials you need from that website.
Once at the Materials website, if you click on the Outline link for any particular week, you will get to a page with a link for the worksheet for that week. You should have a copy of the worksheet with you each Thursday's quiz section.
