*Math 175 Section 5: Calculus II.*

**Instructor:** Andres Caicedo.

**Time:** MTWF 7:40-8:30am. (Ugh!)

**Place:** Business building, Room 217.

**Text:** Hass, Weir, Thomas, *University Calculus*.

**Contents:** Chapters 6-9. I will frequently update this entry with more detailed week to week descriptions. My general plan is a bit ambitious, and leaves a few additional hours free at the end of the semester, where additional topics could be covered. These hours will also act as a buffer in case some topics require more time than originally intended.

- August 25-29: Review of Calculus I, Sections 6.1, 6.2.
- September 2-5: Sections 6.3, 6.4, and half of 6.5.
- September 8-12: Remainder of Chapter 6, Sections 9.1 and half of 9.2.
- September 15-19: Remainder of section 9.2, sections 9.3, 9.4, and half of 9.5.
- September 29-October 3: Chapter 7 up to 7.2.
- October 6-10: Sections 7.3, 7.4, 7.6.
- October 13-17: Sections 7.6, 7.7, 8.9 (only as it concerns to Taylor polynomials and the error terms of these approximations). The discussion of the error term in Simpson’s rule is based on the article “
*Simpson’s rule is exact for quintics*” by Louis A. Talman, American Mathematical Monthly, vol 113 February 2006, pp. 144-155.
- October 20-24: Sections 7.7 and 8.1.
- November 3-7: Sections 8.1-4.

- December 1-5: Section 8.7-8.10.
- December 8-12: Uniform and pointwise convergence of power series, Wierstrass test, infinite products, additional material on the -series .

**Prerequisites:** 170 (Calculus I) or equivalent.

**Exams:** There will be 2 in-class exams and a comprehensive final exam.

- Exam 1: Friday September 26. Should cover Chapters 6 and 9.
- Exam 2: Friday October 31. Should cover Chapters 7 and 8 (up to half of section 8.7).
- Final exam: Monday December 15, 8-10am.

Dates and times are non-negotiable. Failure to take a exam will be graded as a score of 0. There will be no make up for the final exam. For the in-class exams, a make up can be arranged if I am notified prior to the exam date and a valid reason is presented; keep in mind that make up exams will be more difficult than regular in-class exams.

**Homework:** There is weekly homework, due Tuesdays at the beginning of the class. I will frequently update this entry with each week’s homework assignment. No late homework will be graded. Failure to turn in a homework set corresponds to a score of 0. The lowest homework score will be dropped at the end of the term. Some homework sets will have a small amount of extra credit points.

- Homework 1, due Wednesday September 3: From section 6.1, solve exercises 8, 15, 35. From section 6.2, solve exercises 14, 24. Please display all your work, not just the final answer, and explain what you are doing rather than making me guess what you are trying to do. Each exercise is worth 2 points.
- Homework 2, due Tuesday September 9: From section 6.3, solve exercises 14, 30. From section 6.4, exercise 28. From section 6.5, exercises 4, 8, 13, 18, 32, 34. From the practice exercises for chapter 6 (beginning in page 444), exercise 24. Each exercise is worth 1 point.
- Homework 3, due Tuesday, September 16: From section 6.5, exercises #25, 36. From 6.6, #2, 33. From 6.7, #8, 30. From 9.1, #2, 26, 30, 34. From 9.2, #2. The set is worth 10 points, each exercise is worth 1 point, and you can get 1 extra credit point. Please turn in your homework
**at the beginning of lecture, not in the middle of lecture or at the end, not when you arrive to lecture if you arrive late. Starting with this homework set, I’ll be getting pickier on how you write your solutions. Please write them in a reasonable fashion so the person reading them can understand what you are doing without having to go check in the book what formula you are trying to use. Use ****words** if necessary. A long string of equations and implications is not particularly readable, unless the reader already knows what you are trying to do, so try to make your solutions a bit more reader-friendly than they have been so far. This will also help you study later. You may lose points even if you have found the correct answer to an exercise but it is not written appropriately.
- Homework 4, due Tuesday, September 23. Same remarks as above apply. From section 9.2, solve exercsies #12, 24. From 9.3, #23, 30. From 9.4, #26, 44, 69. From 9.5, #38. From the practice section of Chapter 9, #17-24. Each exercise is worth 1 point, except for the combined exercise 17-24, which is worth 2 points.
- Homework 5, due Tuesday, October 7. Same remarks as before apply. Section 7.1, exercises 20, 30, 32, 42. Section 7.2, exercise 40. Section 9.3, exercise 23. Each problem is worth 2 points; there are 2 extra credit points.

Solve as many problems as you want; of those, up to 12 will be chosen randomly and graded. Each exercise is worth 1 point, so you may obtain two extra credit points.

**Section 8.1, e**xercises 86, 88, 127. Also, the following exercise: Starting with a given , define the subsequent terms of a sequence by setting . Determine whether the sequence converges, and if it does, find its limit. More precisely: You must indicate for which values of the sequence diverges, and for which it converges, and for those that converges, you must identify the limit, that may again depend on . You may want to try studying the sequence with different initial values of (choose a large range of possible values) to get a feeling for what is going on. Section 8.2; exercises 14, 22, 38, 40 (do not use a calculator for this one; you can use that if necessary), 64-68, 71. Section 8.3; exercises 26, 35, 41, 43, 44.

**Grading:**

- Homework: 60%.
- Exam 1: 10%.
- Exam 2: 10%.
- Final exam: 20%.

I will then grade on a linear scale:

- If your final score is 90% or higher, you receive an A.
- If it is between 80 and 89%, you receive a B.
- If it is between 70 and 79%, you receive a C.
- If it is between 60 and 69% you receive a D.
- If it is 59% or lower, you receive an F.
- There may be a small curve up if the distribution of scores warrants this. Plus and minus grades might be used for grades near the top or bottom of a grade range.

**Attendance:** Not required, but encouraged. I will use this website to post any additional information, and encourage you to use the comments feature, but I will not post here content covered in class. If you leave a comment, please use your full name, which will simplify my life filtering spam out.

**Core outcomes:** In this class you will be assessed on a wide range of skills. Among these, the following make Math 175 a part of the University Core. By the end of the course, you should be able to:

- Identify and appropriately apply different integration techniques.
- Express solutions using (reasonably) correct mathematical language.
- Know that integration is an inverse operation to differentiation, and can be used to measure lengths, areas, and volumes, among others.
- Formally manipulate power series and justify rigorously these manipulations.
- Solve (separable) differential equations using the integration techniques covered throughout the course, and to express some of these solutions in terms of power series.
