Math-10B, Summer-August-2017. NEWS

Welcome aboard.

1. A remark on grading: The quizzes will be taken into account in a capacity of 60%; the final - 40%. I reserve a right to change it but only in favor of students (say, 70-30 if the final turns out to be tough).

The home works will be collected and “watched”, the fact will be recorded but I will not grade them. Whether a student did the HWs will be taken into account in a “boundary case" when the final grade is not clear. However, a student should realize that

It will be very hard to write quizzes and the final without doing the HWs.

2. On quizzes: Their dates will depend on our pace, but anyway these dates will be certainly announced in advance.

3. On home works: Their material is connected with upcoming quizzes. So, I suggest that at the day of a quiz students turn in the home works connected with this quiz.

4. The first quiz will be on Monday, August 14. It will concern the material of HW-1 (Section 5). Please, look over the graphs of sine and cosine and the values of these function at “most important” points. Students may have a one-page one-side “cheat-sheet” and a non-phone calculator. No phones please.

5. As was told above, students will have to turn in the HW-1 (Section 5) on Monday, August 14, but I strongly recommend to go through all problems by Friday, July 7, to be able to ask me questions (if any) on Friday. In this case, you will be able to prepare yourself for Quiz 1 better.

6. On Monday, August 14, I will run office hours at 10:00-10:50 am for students to be able to ask “last questions” but please be aware that we will have not much time and – again – it is much more reasonable to be ready by the Friday-evening office hours.

7. Our TA, An-Vy Hoang, runs her office hours on Thursdays from 1pm-2pm in AP&M 6436.

8. More about the Monday quiz. Above else, it will include:

(a) A problem on upper and lower sums (please, do not confuse with left and right sums – it is not the same).

(b) Problems on the First Fundamental Theorem of Calculus; how to compute a definite integral of a function f(x) if we know a function whose derivative equals f(x).

(c) Problem on the motion of a body given a graph of the speed of the body.

9. Make notice that the HW-2 has been slightly changed: problems on trigonometric substitution were added.

10. The second quiz will be on Monday, August 21. It will concern the material of HW-2 (Sections 6.1-4, 7.1-3, problems on trigonometric substitution, and one problem from Section 7.4). Students may have a one-page one-side “cheat-sheet” and a non-phone calculator. Above else, the quiz will include:

(a) A problem on antiderivatives;

(b) A problem on the Second Fundamental Theorem of Calculus;

(c) Problems on substitution including trigonometric substitution;

(d) Problems on integration by parts,

11. On Monday, August 21, I will run office hours at 10:00-10:50am for students to be able to ask “last questions” but please be aware that we will have not much time and it is much more reasonable to be ready by the Friday-evening office hours.

12. More remarks on the Quizzes and final: Students should not just use blindly formulas from the book or somewhere else if we did not prove or at least stated them in class. In particular, this means that you can use only the Part I (Basic functions) from the Table on the back of the book.

As to formulas from Parts II and III of the Table, students do not have to know them. All problems in the quizzes and Final do not require much time, and a student, rather than blindly apply complicated formulas, should just demonstrate that she/he knows how to solve problems using methods we discussed in class.

On the other hand, if students use a formula or a theorem we stated in class, they certainly do not have to prove it. It suffices just to refer to it (for example, saying “As was shown in class, …”).

I recommend also to look over examples we considered in class; in particular, those on substitution and integration by parts.

13. The schedule of office hours in the next week: Monday – 10:00am; Wednesday – 10:00am; Friday – 4:10pm.

14. The third quiz will be on Monday, August 28. It will concern the material of the HW 3:

(a) Section 7.4 (more precisely, the method of partial fractions since trigonometric substitutions were considered in the previous quiz), and

(b) Sections 7.6-7 (improper integrals). The material given in the book is enough, but I recommend to look also over examples and statements we will consider in class.

I strongly recommend to go through the whole (or at least, the large part of) HW by Friday to be able to ask all questions on that day in the office hours starting at 4:10pm. We will also have office hours on Monday at 10:00-10:50am.

15. The schedule of office hours in the fourth week: Monday – 10:00 pm; Wednesday – 10:00 am; Friday – 4:10pm.

16. The third quiz has been written not bad at all, though it could be better. To stimulate students to analyze their mistakes and prepare themselves better for the final, I suggest to do correction for Quiz 3. People can (though do not have to) write corrections on a separate sheet of paper, staple it to the quiz itself and turn it in on Friday. If corrections are correct, I will add 20% of the points lost. (A problem: Given x is your scores for the quiz, write the formula for your scores after the corrections.)

17. Students who did not turn in corrections for Quiz 3 yet, still can do it on Wednesday.

18. As I explained in class, I will drop the worst quiz grade but on the condition that the course evaluation response rate will exceed 50%. (Such a condition is not my initiative but rather that of the department. It goes without saying that students are free to write whatever they want.)

19. The final will be comprehensive but the emphasis will be on the topics we did not cover by the quizzes. These topics are most difficult and I strongly recommend students (including those who consider themselves ingenious) to attend lectures.

20. On coming office hours. They will hold on Wednesday at 4:15pm, on Friday at 10 am, and on Saturday at 5:45-6:45 pm.

21. On the final. It will be comprehensive and uniformly reflect practically all topics we covered. I will talk about it in more detail in the last lecture. Students may use a one-sheet two-sided “cheat-sheet”.

My advice to students is first look over all quizzes and make sure that now you know how to solve all problems there. After that you should go over the last HW including sections 11.1, 11.4. There will be a problem on that. In other words, do not skip topics and types of problems we considered. Any problem may come up in the final.

Some emphasis will be on Taylor's approximation. There will be a problem on geometric series, and problems on volumes (including volumes of revolution, that is, on topics from 8.1 and 8.2).
