Kane 210
Final exam stats: minimum 0, 1st quartile: 48.25, median: 62, 3rd quartile: 72, maximum 80(one person).
The grade record has been updated with your final exam scores and your actual course grade, including the dropping of your lowest homework score, the application of the curve, and the section bonus (go AC!) for participation in lecture. If you would like to see your final exam, feel free to stop by any of my office hours after the start of spring quarter. They will be listed here.
Enjoy the break!
I rewrote, simplified and added answers to problem 10 on the final review problems.
Here is a review sheet for the final. It contains some ideas of things to focus on from each section of the course.
Some things for final study:
The Grade Record (pdf) is now available.
Your data is listed by the last four digits of your student id number. The primary purpose of the grade record is to allow you to check that your scores have been recorded correctly. Be sure to check the record. If you find any errors, contact your TA; you will need to show them the homework or exam that was recorded incorrectly.
The grade record contains a current estimated grade. Your lowest homework score was dropped in this calculation. The curve has been applied. This is only an estimate; the curve will change depending on the results of the final exam.
Here is an animation that might help you visualize what's going on in problem 22.5.
Here is an animation showing an idea from Wednesday's lecture. Try reloading if it doesn't animate.
Here is some preliminary data on the latest exam.
| min | 5 |
| 1st quartile | 18 |
| median | 25 |
| 3rd quartile | 30.75 |
| max | 45 |
Here is a very approximate grade translation:
| ≤17 | 0 |
| 20 | 1.3 |
| 25 | 2.7 |
| 30 | 3.1 |
| 35 | 3.6 |
| ≥ 39 | 4.0 |
Here are answers to the second midterm.
Wayne Grey, the TA for AC and AD, is holding a review session on Wednesday from 4:30 to 6:30 PM in Thomson 125. If you go, remember to thank him profusely for this extra effort on his part.
IMPORTANT NOTE: Since we didn't quite finish a decent example of sinusoidal modelling on Friday, I've decided not to include Chapter 17 material (sinusoidal functions) on the second midterm exam. I will probably update the review sheet to reflect this, but note that at the moment it includes chapter 17 material.
When looking at old exams on the test archive, you can safely ignore any problem that contains the word 'sinusoidal' or 'sinusoidally'. This material will will be on the final exam.
Here is a review sheet for the second midterm. The assigned homework is your best study guide, so be sure you understand and can do all of those problems first, before moving on to something else, like the old exams at the test archive.
Here are some statistics on the first midterm exam:
| n | 151 |
| min | 3 |
| 1st quartile | 13.5 |
| median | 20 |
| 3rd quartile | 27 |
| max | 40 (4 people) |
To get an idea of what your score means grade-wise, here is a table of approximate conversions. This table is only for demonstration purposes, I don't use these conversions for anything. The actual curve used will depend on the scores on all exams and homework. This table is just an approximation of the grade you would have if your grade depended only on this first exam.
| <14 | 0.0 |
| 14 | 0.7 |
| 15 | 1.0 |
| 20 | 2.6 |
| 25 | 3.0 |
| 30 | 3.4 |
| 35 | 3.8 |
| ≥37 | 4.0 |
The answers to the first midterm can now be found on the test archive, here.
On Wednesday this week, let's go over questions from the last two Midterm 1 exams in the test archive. In class, I think I said the last two exams meaning Autumn and Spring, but I've not posted the autumn exam, so let's do Spring 2005, and Autumn 2004.
You can get to the test archive by following the materials website link on the right side of the page.
For those looking for a fun challenge, the ACMS program is now offering a weekly (?) Challenge of the Week. Take a look.
Welcome to Math 120! Check this site often during the quarter for announcements, useful information and supplementary course materials. The right side column contains the course schedule. Soon it will have the homework assignments, syllabus and other useful stuff.
