syllabus

• To read: all
• Pay attention to: all of it. Any questions? Please do ask me!

Section 5.1: Areas and Integrals
Section 5.2: The Area Function
Section 5.3: The Fundamental Theorem of Calculus

• To read: All of sections 5.1, 5.2, and 5.3. The main ideas in this section should be review. If you did not take Calc 1 at Wheaton, however, the presentation of the ideas may be quite different from what you're used to -- use this review as an opportunity to get acquainted with the authors' style. Adjusting to a new book can be difficult -- your immediate reaction may be negative, just because it's not what you're used to. Keep an open mind, and remember that one would expect Calculus in college to be different from Calc in high school.

  If the main ideas in these sections are not review to you, please e-mail me or come speak to me immediately.

  If the sections are largely review, but you have one or more questions, please come to my office hours. Office hours are a huge part of Calculus at Wheaton; I expect nearly every one will come see me at least every couple weeks.
  

• Be sure to understand: The statements of both forms of the Fundamental Theorem of Calculus.

Reading questions:

1. Why do you think it makes sense to call
   int(f(x),x=a..b)/(b-a) the average value?

   Notes:

   • The above is written in Maple notation -- it's as good a way as any to write mathematical ideas without symbols, with the added benefit that it gets you used to some Maple notation. The above says the integral of f(x), from x=a to x=b, all divided by b-a.
   • The text doesn't specifically address this question; the reason I'm asking this is because this is exactly the sort of question you should be learning to ask yourself (and attempting to answer) when you read.
2. Find the signed area between x^5 and the x-axis from x=1 to x=2.
3. If f(x) is continuous, must it have an antiderivative? If your answer is yes, does that mean there must be a nice formula (or any formula at all) for the antiderivative?

Reminders:

• In these assignments, you should always briefly explain how you arrived at your answers.
• Begin Problem Set 1, listed at the bottom of this course's web page. . The problem sets due each Tuesday reflect an entire week's worth of work, and you should be working on them throughout the week.

Please Note:

Reading assignment submissions whose subject headings exactly match the filters I've set up should receive a response letting you know I've received it. If you don't receive such a message, it might mean I didn't get your response, but it might also just mean that your subject heading didn't match my filters. If you don't receive a response, just check with me now and then to make sure I've gotten everything you've sent in. Sometimes messages do seem to just disappear, so (if your "sent-mail" box is emptied everynow and then, or if you're not sure about that) send yourself a copy of every reading assignment, just in case you need to re-send one to me.

Due Monday 1/30 at 9am

Problem Set Guidelines
Section 3.4 Inverse Functions and Their Derivatives (Appendix S in your book, I believe)

• To read: You can skim the beginning of Section 3.4 (Appendix S), but carefully read the section Working with inverse trigonometric functions beginning on page S-8.

E-mail Subject Line: Math 104 Your Name 1/30

Reading questions:

1. What is the domain of the function arccos(x)? Why is this the domain?
2. Explain how we can tell lines which are neither horizontal nor vertical have inverses.
3. Why do you think we are studying the inverse trig functions now?
4. Find one antiderivative of 1 / (1+x²).

• If you have any last remaining questions on the problem set after coming to my office hours, bring them to class Monday.
• Make sure you've read all the stuff I handed out in class and all the material on the course web page.

Due Wednesday 2/1 at 9am

More on Antidifferentiation & Inverse Trig Functions

• To read: Re-read any sections we've read so far that have caused you difficulty. If you're feeling not-quite-ready for this class, this is your day to catch up.
• Be sure to understand: Everything

No Reading Questions Today

Reminder:

• Begin working on PS 2. This is a group assignment -- that means you must work with one other person (or in some cases, two other people). Start introducing yourself to people in the class, and try to find someone you think you can work well with.

  These groups are not permanent -- you're welcome to work with different people different weeks.

Due Friday 2/3 at 9am

Section 5.4 Finding Antiderivatives; The Method of Substitution

• To read: All. Remember to pay attention to tables and graphs; in particular, remind yourself why all of the basic antiderivatives in the table on page 333 are true, and begin to know them all.
• Be sure to understand: Examples 6, 7, 9, and 13 illustrate specific important points, but you should be paying attention to and doing your best to understand all the examples.

E-mail Subject Line: Math 104 Your Name 2/3

Reading questions:

1. Explain the fundamental difference between a definite integral and an indefinite integral. Please go deeper than saying one has limits of integration and one doesn't. The first is a real number -- why? what does it represent? Then think similarly about indefinite integrals.
2. Substitution attempts to undo one of the techniques of differentiation. Which one is it?
3. What are the three steps in the process of substitution?

Reminder:

• Remember the problem sets due each Tuesday reflect the whole week's worth of work, and should be worked on throughout the week.
• As I mentioned before, office hours are an important part of Calculus, so please don't hesitate to come to them! I only set aside 10-15 minutes in class on Mondays to answer questions on the week's problem set, so don't save all your questions for that time--come to office hours, and get more personal attention.

Due Monday 2/6 at 9am

Section 5.6 Approximating Sums; The Integral as a Limit

• To read: All

E-mail Subject Line: Math 104 Your Name 2/6

Reading questions:

3. Explain the idea of a Riemann sum in your own words.

Reminders:

• The Kollett Center for Cooperative Learning (KCCL) has office hours held by student tutors. As you can see, each of the Calculus classes has some hours that are listed as being priority for that class, but you're welcome to go to any of the Calculus hours. If you go to hours whose first priority is one of the Calc 1 or multivariable classes, you simply need to wait until those students have their questions answered.
• After coming to office hours and/or going to the KCCL for the tutoring hours, bring any still-unresolved questions on PS 2 to class on Monday.
• (Last reminder of the semester:) Come to lab Tuesday at 1pm, bring your completed problem set with you.
• Your group will turn in one joint version of PS 2; the recopying should all be done by one person, the "primary author". Make a note on it who the "primary author" was this time, and switch next time.
• Be sure that each member of your group has a photocopy of the problem set you turn in, both for studying purposes and for your records.

Reminders:

• Take advantage of my office hours as well as tutoring hours for help resolving any questions, whether big or small, subtle or major. Every semester it turns out someone is embarrassed to come to me for help, because they feel like they should have come earlier. Please don't worry about it -- better now than later, and better late than never.
• PS 4 will not be turned in, but it will be covered on the exam. Get questions on it out of the way before class!
• For the exam, you may have a "cheat sheet", consisting of handwritten notes on one side of an 8 1/2 x 11 (or smaller) piece of paper.
• You may begin taking the exam at 12:30pm Tuesday.
