- Exercises: Section 2.1 # 15, 16, 21, 23
- Remarks: In these exercises, the student is asked to find function values and limits for functions f and g that are given by graphs (not given by formulas). One could visualize the idea of these problems with an arrow diagram:

- Exercises: Section 2.1 # 33, 35, 37
- Remarks: In these exercises, the student is asked to find function values and limits for functions that are given by graphs formulas. The idea is to use Theorem 2 (Properties of Limits) and Theorem 3 (Limits of Polynomial and Rational Functions). The main point of the "solution" of problems like these is to show each application of a Theorem on its own line, with the particular Theorem cited by number (such as Theorem 2.6). (See book examples and class notes for models.) In all three of these basic exercises, the value of the limit at x=c ends up equaling the function value at x=c. But again, the limit is to be computed by using the Theorems and citing them in the written solution, not simply by just substituting in x=c.

- Exercises: Section 2.1 # 51, 53, 57, 91
- Remarks: In these exercises, the function is a piecewise defined function. That is, the domain of the function is broken up into two or more pieces, and the formula that describes the function is different on each piece. In problems #51 and #53, the piecewise definition is explicit: The pieces of the domain are presented clearly, and for each piece of the domain, the formula for the function is given clearly. Problem #57 is not presented as a piecewise-defined function: the formula is just a single expression. But notice that the expression involves the Absolute Value Function. In order to work with the Absolute Value fFnction, you will have to realize that it, too, is a piecewise-defined function. (The piecewise definition of the Absolute Value Function is given just before Example #3 on page 97.) Problem #91, about Telephone Rates, asks the student to come up with a piecewise definition of the charge function F, and then graph it and answer questions about its limit behavior.

- Exercises: Section 2.1 # 61, 63, 77, 79
- Remarks: In these exercises, the function is a rational function. A crucial concept is the distinction between the function value at x=c and the limit at x=c. In some problems, the function value does not exist at x=c but the limit does exist at x=c. But in other problems, niether the function value nor the limit exists at x=c. Perhaps the most important concept of the first month of the course is the idea that sometimes one cannot cancel expressions when computing function values (if the expressions result in 0/0), but can cancel those same expressions when computing limits. The book does a lousy job with this concept in Section 2.1. In Example 8, the book says that "...Algebraic simplification is often useful ...", but this is very vague and does not address the underlying issue. The "Conceptual Insight" at the top of page 103 attempts to explain the concept. But nothing is mentioned about the fact that when one is actually computing a function value (not computing a limit), one is not allowed to cancel. In lecture, I will be very explicit about the important underlying concept. And I will be very clear in lectures about how I expect these sorts of problems to be written. It is important that in your solutions, you explain the important underlying concept clearly. (Again, note that the book solutions do not explain the underlying concept at all. So I will be expecting your written solutions to be more thorough than the solutions presented in the book!)

- Exercises: Section 2.1 # 81, 83
- Remarks: In these exercises, the student is given a formula for a function f and must build a Difference Quotient for f and then take a limit of that Difference Quotient. The calculations are difficult, and they seem rather random: the book mentions that Difference Quotients are "important", but does not explain why they are important. It turns out that Difference Quotients are central to the upcoming definition of the Derivative in Section 2.4.

Formula for Function ==> Description of Limit Behavior
In these exercises, sometimes the limits turn out to be real numbers. In these cases, the limits are the same as the kinds of limits that are discussed in Section 2.1. But in most of the exercises, the limits turn out to involve infinity or to not exist. Also note that in the textbook examples, limits like these are explored by substituting x-values into the function f(x) and computing the resulting y-value using a calculator. The reader would get the impression that without a calculator, there is no way to determine this sort of limit. But in Class Meeting #3 and Class Drill #3, a method of determining infinite limits without a calculator is presented. This method gives a much better understanding of how the limits work.

This kind of problem has been encountered before, in Section 2.1 Exercises # 47,49. The added twist in the current section is that the student is also asked to discuss the continuity of the function.
- Relevant Reading: Recall that in textbook Section 2.1 there was no discussion of problems involving drawing a graph that has prescribed limit behavior.

- Useful Book Examples: Section 2.5 Examples 5bc (and corresponding Matched Problems)
- Useful Lecture Notes: Class Meeting #12
- Exercises: Section 2.5 # 45,51,53,55,81
- Remarks: In these problems, the function is presented in a form involving fractions. In this form, the derivative rules cannot be used to find the derivative. One must first rewrite the function as a sum of terms that are each of the form of a constant times a power function. With the function rewritten this way, the derivative can be found easily. The initial step of rewriting the function in a more useful form is a very important step, one that will be necessary in many problems throughout the rest of the course. This initial step relies only on arithmetic and algebra skills from prerequisite courses. Even so, many students have trouble with this step and as a result, are unable to find the derivatives in many of the problems that they encounter. So I encourage you to work very hard on this group of problems.

- Exercises: Section 2.5 # 89,91,97
- Relevant Reading: Section 2.5 pages 147 - 152 presents the necessary derivative techniques.
- Useful Book Examples: Section 2.5 does not include any examples asking the student to "...write a brief verbal interpretation of these results." But back in Section 2.4 Excample 8 (at the bottom of page 141), the student is asked to "...Find and interpret S(25) and S'(25)." The worked solution to that example gives an idea of what is meant by an "interpretation". You will need to read the solution to that example carefully to find the "interpretation". At the bottom of page 141, the author finds S(25) and S'(25). The "interpretation" of these two quantities is presented in the first sentence at the top of page 142.
- The author found that S(25) = 7, which is a number. The interpretation is that 25 months from now, the total sales will be $7 million. The units in this sentence are millions of dollars.
- The author found that S'(25) = 0.1, which is another number. The interpretation is that 25 months from now, the sales will be increasing at athe rate of $0.1 million per month. The units in this sentence are millions of dollars per month.
Observe that S(25) and S'(25) are simply numerical values, while the "interpretation" is a sentence that explains what these numerical values tell us about the company's sales. Also observe that the "interpretation" sentence uses appropriate units.
- Notice that the function S(t) was defined to represent the company's total sales (in millions of dollars) t months from now. And notice that the interpretation of the the meaning of the value S(25) consisted of a sentence that used the units millions of dollars.
- A key concept in this course is that the value of the derivative represents a rate of change. To figure out the correct units for the rate of change, one simply divides the unit of the function (millions of dollars, in this example) by the unit of time (months, in this example). But in my opinion, the author could have interpreted more clearly. To say that "...total sales ... are increasing at a rate of $100,000 per month" is not as clear as it should be. What does it mean that ...total sales...are increasing? How do total sales increase? They increase by selling products. So it might be clearer to say that "...the company's products are selling at a rate of $100,000 per month.".
- Useful Lecture Notes: The idea of "interpretation" will not be covered in lecture during the discussion of Sections 2.4 and 2.5. You will need to read the book carefully (and read my remarks above) to learn about it when studying Section 2.5. But we will be discussing the topic quite a bit when we get to Chapter 3.

- Remarks: I find the book's Section 4.1 to be very badly organized. The reading does not present concepts in a progressive manner, starting with simple concepts and then building on them to develop more sophisticated concepts. Rather, the concepts are presented in a rather random order. For instance, what I find to be the most important starting concept, that of correlating the increasing/decreasing behavior of a function f to the positive/negative behavior of its derivative f ', is scattered throughout the section. Simple examples involving recognizing increasing/decreasing behavior in a given graph of f do not show up until Examples 6 and 9. Furthermore, the ordering of exercises in the book does not correspond to the ordering of the presentation of the concepts in the reading. As a result, Section 4.1 tends to be one of the most difficult sections to cover in lecture, and one of the most difficult sections for students to understand. My lectures in Class Meetings #27, 28, 29 attempt to remedy this by re-ordering the presentation of the material. As much as possible, the exercise groups for Section 4.1 presented here correspond to the presentation of concepts in my lectures.

- Remark: These problems are in the same style as the exercises in Section 5.1 Group 1. That is, the questions use the terminology of antiderivatives, but to answer the questions, one need only find derivatives. No indefinite integrals are needed. Notice that there is no discussion of this sort of problem in the current Section 5.2. The student need only review the textbook reading and class notes for the exercises in Section 5.1 Group 1. That material is listed again here:

- Remark: Note that the book discusses Left Sums and Right Sums mostly. And that's what we'll discuss in class. It is unfortunate (and silly) that the book does not include any exercises involving finding a Left Sum or Right Sum for a function given by a formula. Exercises #23,24,25,26 all deal with more complicated Riemann sums. Of these four exercises, Exercise #23 is the simplest, because it involve a midpoint sum. Example #2 on page 357 is similar.
