Midterm 1: Thursday, April 24
Midterm 2: Thursday, May 22
Final Exam: Saturday, June 7
1:30-4:20 PM, Kane 120
Here is the updated grade file, with final exam scores and course grades. These are the grades I will be reporting to the registrar. They include the course curve, and the dropping of your lowest quiz and homework scores. Note that those lowest scores appear in the record, but were dropped during the calculation of your grade. Statistics on the final exam are given in an entry below.
Have a good summer!
Grade posting has been a little delayed: they will be posted this evening.
Special post-final office hour: Friday, June 13, 1-2 PM for viewing of final exams.
Statistics on the final exam: n=133; min=13; 1st quartile=44; median=52; 3rd quartile=62; max=80 (one person).
Grades should be posted later this week, Thursday evening or Friday morning. I will have an office hour on Friday in the afternoon: I'll post the hour this week.
Here is a review sheet covering the whole course.
The grade record is now posted.
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 current estimated course grade. This includes the course curve, and the dropping of your lowest homework score and the dropping of your lowest quiz score (note that your lowest scores appear for the sake of record, but were dropped during the calculation of your current estimated grade). Obviously it does not include the final exam: that can have a very large impact on your actual course grade.
If you did not take one of the two exams, and have made arrangements with me to compensate for this, the grade estimate is not accurate. Too much depends on how you do on the final exam to give a useful estimate.
Here are the answers to midterm 2.
Here are some partial statistics for the second midterm exam.
n=70, 1st quartile=31, median=34, 3rd quartile=38, maximum=40 (several people).
People generally did quite well! Keep up the good work - the final exam is less than two weeks away.
I'll be posting estimated current grades for each student in the course later this week.
Here is a review sheet for the second midterm exam.
When using old exams to study, keep in mind that they may include problems related to chapter 18 material. Any question I might ask you about sinusoidal functions would likely require you to determine the function and perhaps evaluate it at a specific time (as the problems in chapter 17 do). If you encounter a chapter 18 question on an old exam, you can still use it for practice in finding the sinusoidal function.
Here is an example of the kind of calculation you need to do to determine a specified linear-to-linear rational function.
Answers to the first midterm exam are here.
UPDATE: these answers have been updated due to an error (problem 1 of version B).
Here are the stats from the first midterm exam:
n = 153
minimum=2
1st quartile = 18
median = 25
3rd quartile = 31
maximum = 40 (1 person)
Here are some rough guidelines for translating your exam score into a 4.0-scale grade. This is only approximate; basically this is what your grade would be if I had to assign grades now based just on this exam.
| ≥37 | 4.0 |
| 33 | 3.5 |
| 28 | 3.0 |
| 24 | 2.5 |
| 21 | 2.0 |
| 17 | 1.5 |
| 14 | 1.0 |
| ≤12 | 0.0,/td> |
If you got a score of 20 or less, you definitely have a lot of work cut out for you if you intend to pass this course with a 2.5. I recommend coming to office hours to discuss whether or not you can recover from this exam, and if so, what you need to do.
Here is a review sheet for the first midterm exam.
The answer in the textbook for 7.11 is incorrect. The correct answer is that the radius of the circular part of the window should be 24/(4+Pi) feet, which is about 3.36059492 feet.
I have changed the homework schedule slightly: problem 4.12 is no longer due this week. It will be due next week. Please don't turn it in this week.
I will give some suggestions for solving it in lecture on Wednesday.
