Announcements for the week of 3/1-3/5:
There will be a makeup test offered at night in a couple weeks, for students who want to improve their grades. It will be a three-hour, five question test, similar in format to Midterm 1. (I was always secretly planning to do this.)
The makeup test will be on Wednesday, March 24, from 8-11 p.m., in P-131 Math, on the ground floor of the Math Building. You will not be allowed to leave before 8:30. You will not be allowed to arrive after 8:30. If you arrive before 8:30 you will be allowed a full three hours -- so people with classes until 8:10 will be accomodated.
Your grade on the first midterm will be the maximum of the two grades from March 5 and March 24.
Homework (due in recitation on Thursday 3/11): Chapter 3, #1, 2, 3, 5, 6, 7.

Announcements for the week of 3/8-3/12:
Homework (due in recitation on Thursday 3/18): Chapter 4, #2, 4, 6, 7, 8, 9

Announcements for the week of 3/15-3/19:
Please note the following:
1. The test on March 24 will cover Chapters 1 and 2 only.
2. Jan Gutt's review sesson for the makeup test will be on Wednesday, March 24, from 3:30 to 6:30, in P-131 Math (the large room on the ground floor of the Math building). You can come and leave at any time during the review session.
3. This week's homework (due in recitation on Thursday 3/25) is: Chapter 4, #15, 17, 18, 23, 25, 27.

Announcements for the week of 3/22-3/26:
I have graded the makeup midterm. Please send me an e-mail if you would like to know your grade. Don't be shy!
Please note the following schedule for the week right after the break:
Monday, April 5: recitation during the usual lecture time (in SB Union 231)
Tuesday, April 6: lecture during the usual recitation time (in Physics P112)
Wednesday, April 7: regular lecture
Thursday, April 8: regular recitation
Friday April 9: second midterm , during usual lecture time, covering up to the end of section 5.3. The test will highlight the material after Chapter 2, but, as you know, math is cumulative (especially this course).

Please be sure to always check the "Approximate Course Schedule" at the bottom of this web page, to ensure that you know which sections of the book we are including and which we are leaving out.
Homework (due in recitation on Monday 4/5) is: Chapter 5, #1, 2, 6, 7, 9, 12, 14; also, Chapter 4, #13, 14 (on page 154).

Announcements for the week of 4/5-4/9:
Approximate midterm scoring guides:

For Test 1 (on March 5) (out of 60):
50 and up: A or A-
40-49: B+. B or B-
27-39: C+ or C
19-26: C- or D
0-18: F

For the makeup test (on March 24) (out of 100):
85 and up: A or A-
65-84: B+, B or B-
45-64: C+ or C
30-44: C- or D
0-29: F

Your grade on the first midterm is the higher of the two grades that you received on the two tests (March 5 and March 24).

If you're a math major, and you'd like to use either of these tests to satisfy part of your writing requirement, that's great, but please contact me before the semester ends. If you ask me after the semester ends, my answer is going to be "no".

The Second midterm will be held in class, this Friday, April 8. I have no plans whatsoever to give a makeup for the second midterm. The test covers the material up to and including section 5.3. The test will highlight the material after Chapter 2, but, as you know, math is cumulative (especially in this course).

For the second midterm, you will be asked to prove things, but you will also be asked to state some definitions and statements of theorems. So make sure you know the definitions, and statements of theorems, perfectly. You are also responsible for knowing the proofs of the theorems that we have proved in class, especially Theorem 5.15 on pages 221-224. (I'm not going to ask you to reprove anything we have proved in class, though). Mostly I will focus on the main points, but be sure that you know what it means for a function to be j.a.e. differentiable.

My office hours for the rest of the week are: Wednesday and Friday, 10-10:30 a.m., and Wednesday, 1:15-2:45 p.m. This is a change in my office hours, for this week only.

There is still space on the bus for this Saturday's Undergraduate Mathematics Conference. It looks very interesting -- there will be talks on the mathematics of climate change and on "Can Computers do Math"? If you're interested in going, please contact Professor Moira Chas at moira@math.sunysb.edu.

Homework (due in recitation on Thursday 4/15) is: Chapter 5, #22, 24, 25, 25.5, 29, 30.

Announcements for the week of 4/12-4/16:
The second midterms will be handed back in recitation on Tuesday, 4/13. It was out of 60, with each question counting 20 points. To determine (roughly) your grade so far, first calculate your total score so far as follows. Let:
a = your score on the test on March 5.
b = your score on the test on March 24, times .6
c = the maximum of a and b
d = your score on the test on April 9
e = c + d. This is your total score so far, out of 120.

Now, calculate (approximately) your grade so far:
If your total score so far, out of 120, is:
100 and up: A or A-
80-99: B+. B or B-
54-79: C+ or C
38-53: C- or D
0-37: F

So far, no one has been affected by the "perfection" score.

As you can see, there is no curve in the course. However, the final exam will be an opportunity for some people to possibly raise their grades, because:
-- there will be some epsilon-delta limit proofs;
-- there will be some questions on determining whether series converge or diverge;
-- the exam will be taken out of 100, but the total number of points available will exceed 100;
-- there will be two and a half hours for the exam;
-- like many professors, I look favorably upon students who were not doing so well during the semester, but improve on the final exam.

Homework (due in recitation on Thursday 4/22) is: Chapter 5, #15, 16.5, 18; and Chapter 6, #3, 4, 6, 7.

Announcements for the week of 4/19-4/23:
Homework (due in recitation on Thursday 4/29): Chapter 6, #8, 9, 10 (a)(b)(c), 12(b)(c), 13, 15(a)(b), 22.

Announcements for the week of 4/26-4/30:
Homework (due in recitation on Thursday 5/6): Chapter 6, #23, 25, 26, 27, 28(b)(d), 34, 35, 36. In #36, do not prove convergence.

Announcements for the week of 5/3-5/7:
The final exam will be held on Wednesday, May 12, from 11:15 a.m. - 1:45 p.m., in our usual classroom.
You need to know the first three chapters of the book perfectly, since up to 50% of the points needed for a perfect score will be based on them. Make especially sure that you know exercise #37 on page 92, and problem #5 on the makeup for the first midterm. As for chapters 4-6, here is a crucial study guide.
Make especially sure that you know the convergence tests for series, especially the limit comparison test, and that you know the chart on page 331, and that you know how to do exercises 25, 26, 27 and 28 on pages 333-334.
Jan Gutt will be holding a review session in P-131 Math, from 4-6 p.m. on Monday, May 10. The room is the large seminar room on the ground floor of the Math building, behind the elevators.
My own office hours for exam week will be from 10 a.m. - 1 p.m. on Tuesday , in my office, 4-100B Math.
