Math 2243: News and Announcements

o 08/09/04: The results of the final: maximum score = 195 out of 200, mean = 122.7. I have submitted the grades to the registrar. They will be available to you online in 24 hours. Have a great summer!

o 08/06/04: I hope to have your grades submitted by Tuesday. Have a great summer. It was a pleasure to meet you all. Good luck!

o 08/03/04: A sample final is posted! It will be discussed Thursday in class.

o 08/02/04: Coverage for the Final, Friday, August 6: everything covered by the four midterms plus 8.6-8.8. That is 1.1-1.8, 2.1, 2.3-2.6, 3.1-3.6, 4.1-4.3, 5.1-5.6, 6.1-6.2, 6.5-6.7, 8.2-8.8. I am working on a sample final.

o 08/02/04: The average score on Midterm 4 is 55.6. However, since the exam was harder than the previous three, I decided to prorate your score to match the 73 average of the previous exams. Thus, you should multiply your score by 73/55.6. For example, if your actual score happened to be 55.6, your prorated score would be 73. If your actual score is 93 (which was the top score), you will get 122.1, that is to say, 22.1 points of extra credit.

o 07/27/04: A sample midterm exam IV is posted. It is a good time to work on it, as well as start getting ready for the test by solving as many problems as you can. Count this also as preparation for the August 6's final. We will discuss the sample midterm Thursday.

o 07/26/04: Coverage for the next midterm, Friday, July 30: 5.6, 6.1-6.2, 6.5-6.7, 8.2-8.5 (through p. 470, the real eigenvalues case). I am working on a sample midterm.

o 07/20/04: The average score on Midterm 3 is 75.3.

o 07/16/04: There was a misprint in the homework assignment to Section 5.6: it should be problem 34 instead of 35. It is now corrected on the homework page.

o 07/15/04: Thanks to Ashley, who made this request, I am now posting answers to even-numbered problems (starting from Section 3.5) on the Class Outlines page of our class web site.

o 07/12/04: Coverage for the next midterm, Friday, July 16: 3.5 (Homogeneous Linear Systems), 3.6, 4.1-4.3, 5.1-5.5. I am working on a sample midterm.

o 07/09/04: I have posted a new homework schedule, adjusted for July 5. Click here to [view] and here to [print].

o 07/06/04: The average score on Midterm 2 is 73.8.

o 06/30/04: I have removed the last part of Section 3.5 from the second Midterm's coverage, see a note below. The average score on Midterm 1 is 72.9.

o 06/28/04: The next midterm is coming pretty soon: Friday, July 2, during the first period. Coverage: Sections 2.6, 3.1-3.5 (not including Homogeneous Linear Systems from 3.5). How to get ready: the more problems you solve, the better you are prepared. Keep handing your homework in for grading. I will post a sample midterm on the web by Wednesday's class.

o 06/28/04: Some corrections are due. On the syllabus, the class coverage for Chapter 1 is through 1.8 rather than 1.6. The answer to Problem 2.4.7 in the textbook is incorrect. The correct answer is what you get, if you do it right;-)

o 06/23/04: A sample midterm is posted. We will discuss it Thursday in class. Do not forget to hand in homeworks at the end of each class meeting. If you do not do it, you will wish you did it, when doing the midterm exam!

o 06/18/04: The first midterm is coming: Friday, June 25, during the first period. Coverage: Sections 1.1-1.8, 2.1, 2.3-2.5. How to get ready: the more problems you solve, the better you are prepared. Solve problems from the homeworks again (if you feel you do not remember how to do them) and similar problems from the text (for example, if problem 11 was on the homework, problems 10 or 12 will likely be similar).

o 06/18/04: Good news! We have got a homework grader for the class, which means that the homework from now on will be collected after each class and a small selection of problems will be graded. ("Small," because the grader will allocate only 6 hours per week for our class.) The homework grade will not be taken into account, so that the whole enterprise is for your sheer benefit: the necessity to hand in your homework will keep you better organized, while having your homework graded will let you see whether you have done it right.

o 06/15/04: Free tutorial services are available. This is a perfect way to get help with your homework, exam preparation, and brush up on those derivatives and integrals! Get a pink handout from me or call the Taylor Center at 624-2890 for more information.
