Math 2243: News and Announcements

12/14/08: A Sample Final is posted. Test yourself before the actual test!

12/09/08: I have removed the last two pages of Section 10.3 from the Final Exam coverage, see below.:-)

12/09/08: Here is Midterm Exam IV statistics: mean = 23.2, median = 22, max = 34 out of 40 points.

12/05/08: The Final Exam is coming: Tuesday, December 16, 6:00-9:00 p.m. in our usual classroom, VinH 20. Coverage: Sections 1.1-1.5, 2.1, 2.3-2.5, 3.1-2, 3.4-7 (through p. 216), 4.1-3, 5.1-3, 5.4 (omit the Simple Pendulum on pp. 322-323), 5.5 (omit Theorem 1 on p. 345), 5.6 (omit Modeling Mechanical Systems on pp. 352-354), 6.1-2, 7.1-4, 10.1-3 (through p. 594). How to get ready: the more problems you solve, the better you will be 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). Test yourself on the Sample Final, which is to be posted soon.

12/05/08: I have changed plans for the last class meeting a little bit. I will not post a sample Final before then, and therefore we will not discuss it in class on Tuesday, December 9. We will discuss Solutions to Midterm Exam IV and study Section 10.3. Afterwords, I will post a sample Final with answers. Should you have any questions, do not hesitate to ask.

12/02/08: Here is Midterm Exam III statistics: mean = 28.4, median = 29 out of 40 points.

11/26/08: I have posted the Sample Exam IV, which we will be discussing on Tuesday, December 2. The most beneficial way to approach it is to solve it on your own before coming to class and then compare your solutions to those of mine.

11/25/08: I have removed Section 10.2 from the coverage for Midterm IV and reworked the schedule for the rest of the term slightly, see the "Class Outlines." Have a great Thanksgiving!

11/25/08: The fourth and last midterm is coming: Thursday, December 4, during the first class period. Coverage: Sections 7.1-4 and 10.1. How to get ready: the more problems you solve, the better you will be prepared. (I have noticed that those who did well on the homeworks did much better on the first midterm in most cases.) 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). Test yourself on the Sample Exam IV, which is to be posted soon.

11/12/08: For problems of the homework due 11/13/08, graphing is not required.

11/11/08: I will be out of town November 18-20, giving a colloquium at University of California, Riverside. Professor Sergey Bobkov will be substituting for me in classes that week.

11/09/08: The Sample Exam III now includes answers.

10/30/08: The third midterm is coming: Tuesday, November 11, during the first class period. Coverage: Sections 5.1-3, 5.4 (omit the Simple Pendulum on pp. 322-323), 5.5 (omit Theorem 1 on p. 345), 5.6 (omit Modeling Mechanical Systems on pp. 352-354), and 6.1-2. How to get ready: the more problems you solve, the better you will be prepared. (I have noticed that those who did well on the homeworks did much better on the first midterm in most cases.) 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). Test yourself on the Sample Exam III, which is already posted.

10/23/08: Here is Midterm Exam II statistics: mean = 34.36, median = 35 out of 40 points.

How to get ready: the more problems you solve, the better you will be prepared. (I have noticed that those who did well on the homeworks did much better on the first midterm in most cases.) 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). Test yourself on the Sample Exam II.

09/25/08: Here is some Midterm Exam I statistics: mean = 31.875, median = 33.5 out of 40 points.

09/19/08: Answers to the Sample Midterm are now inserted in the exam printout. Note that, I have slightly changed Problems 3 and 4, so that it would be easier to solve them without a calculator. Print the version with asnwers out clicking on Sample Exam I. Reload the page, if the old exam (of September 18) pops up. The exam with answers dates September 19.

09/18/08: A Sample Exam I is posted. Test yourself before the actual test!

09/16/08: The first midterm is coming: Tuesday, September 23, during the first class period. Coverage: Sections 1.1-1.5, 2.1, 2.3-2.5. How to get ready: the more problems you solve, the better you will be 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). Test yourself on the Sample Exam I.

09/11/08: Free tutoring services are now available, see information at www.math.umn.edu/undergrad/tutoring_schedule. There are tutors specifically for Math 2243 and 2263, tutors in selected dormitories, tutors by appointment, tutors in Wlater Library, and private tutors for hire.

09/04/08: I recommend the following way to study after each class. First, study your class notes. Next, study the corresponding section of the text. See the Class Outlines to find out which section. Then do the homework.

09/01/08: Homework 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.

09/01/08: 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! See the Math Tutoring page for more info.
