Final grades have been posted. If you go to Telesis, you should be able to see your overall score for the class under the heading "Calculated Final". This score was computed from your exam, quiz, and homework scores according to the percentages on the syllabus. The grades were assigned using the following cutoffs: A 89, A- 85, B+ 81, B- 75, C+ 70, C 64, C- 60. Thanks for a great semester, and good luck in the future.

Contrary to my announcement below, there is no class on Monday. Instead, there will be a review session Monday 1-3pm in Cupples I 199. Email me if you have specific problems or topics that you would like me to go over.
April 23, 2008
The final exam will consist of 20 multiple choice questions and no written portion. It will be cumulative, but approximately 40% of the problems will cover material from Chapter 12. Here is an exact copy of the standard normal distribution table that will accompany the exam. You will be allowed to bring a 4x6 notecard and a scientific calculator to the exam. As usual, I recommend you review the Webwork problems, quiz problems, suggested problems, and the examples from lecture. Since the exam is cumulative, it is also a good idea to review the midterm exams. Monday's lecture will be review. Email me if you have specific problems or topics that you would like me to go over.

The total scores for exam 3 are now up on Telesis. All three of the written problems were graded out of 15 total points, which means that there were 5 "bonus" points available.
April 4, 2008
Tuesday's exam will cover all the material since the last exam. The topics in Chapter 10 are: Linear differential equations, applications (particularly bank account/loan problems, Newton's Law of Cooling, and mixing problems), and Euler's method. The topics in Chapter 11 are: Taylor polynomials, geometric series, integral test, comparison test, estimating sums with integrals, and Taylor series. As usual, I would recommend you review the Webwork problems, quiz problems, suggested problems, and the examples from lecture. The rules for the exam are the same as usual: you can bring a 3x5 notecard and a scientific calculator. Just to warn you, there are 3 written problems this time. There are still 12 multiple-choice problems, but to compensate for the length I have tried to make the multiple-choice problems less computationally-intensive. But when taking the exam, keep in mind that you will require more time than usual for the written problems. Monday's lecture will be review. Email me if you have specific problems or topics that you would like me to go over.

Solutions for the 2nd exam are here. Exams scores are now available on Telesis, and the written portion of the exam will be returned in class tomorrow. Midterm scores have been assigned, based on your two exams and your quiz average so far. The three numbers were averaged together, and the letter grade was assigned using a scale that's similar to the one on the syllabus. The midterm grade is purely advisory and does not appear on your permanent record. Its sole purpose is to give you an indication of how you are doing so far.

I just checked with the department chair, and he says that the exam is still happening tonight. If anything changes, I will immediately post an announcement about it here, but for now you should plan on coming in for the exam.
February 26, 2008
The second exam will cover everything we've done since the last exam; see the schedule for a list of topics. As usual, you should use the suggested problems, webwork problems, quiz problems, and examples from lecture as material for study/practice. Monday's lecture will be review. Email me if you have specific problems or topics that you would like me to go over.

The scores for Exam 1 multiple choice on Telesis have now been updated to reflect the fact that the correct answer to #11 was (i), not (h).
February 8, 2008
The scores for the first exam are now available on Telesis. There may be a discrepancy between your multiple-choice scores on Telesis and on mathlookup; the difference should be explained by the following adjustments: 1) the answer to #7 was (c), not (g), and 2) for #12 we accepted all answers as correct. The score on Telesis is the definitive one. See the course syllabus if you want to know what letter grade your score corresponds to. If your grade was lower than you would like it to be (especially if you got a D or F), then you should consider your options for getting help (see the bottom of the syllabus).

The first exam will be Tuesday, Feb. 5, 6:30-8:30pm. You can look up your seating assignment on the day of the exam here. Some info and comments about the exam:
- The exam will cover sections 7.1-7.4 in the book. But note that there are a couple of additional topics that are not in the book. Those topics are: domains of functions of 2 variables, and optimization with constraint inequalities (this last one is the subject of Friday's lecture). These extra topics are covered by the webwork problems (including set03, which will be available soon).
- It will consist of 12 multiple choice problems and 2 free response problems. The free response problems count for 40% of the score, so you might consider doing them first.
- You are allowed to bring a 3x5 notecard and a scientific (not graphing) calculator, although a calculator won't be necessary to solve any of the problems in this exam.
- For review problems, focus on the suggested problems, the quiz problems, the webwork problems, and the examples from lecture.
- Monday's lecture will be review. It will be best if you email me in advance which problems you would like me to go over.
- Last but not least, the polls will be closed when the exam finishes, so don't forget to vote earlier in the day!

I am adding "suggested problems" for each section on the "schedule" page. The schedule will, of course, be updated as the semester progresses, so be sure to check back regularly.
