# Math V46, Spring 2017

## Introduction and Announcements

Welcome to Math V46 (Applied Calculus) at Ventura College. Michael Bowen (email) will be teaching this course during the spring 2017 term.

Important note: This web page is not a substitute for attending class; regular attendance is an expectation of this course. Modifications to homework assignments, and other important news announced in class, may not appear on this page for several days. You are still responsible for all assignments and in-class announcements even if they do not appear here! If you wish to verify information on this page, please contact the instructor.

## Textbook Information

The ISBN number is provided as a convenience if you wish to purchase this item online. The VC bookstore may stock a different ISBN number; either may be used for the course. If you buy from the bookstore, obtain the least expensive version you can find; do not pay extra for MyMathLab, WebAssign, or other software. If you obtain the book from another source, please be sure to obtain the correct edition, as noted below. Older editions are, of course, much less expensive, but the homework problems are different.

Select any one of the following required texts:

• Author: R. Barnett
• Title: Calculus for Business, Economics, Life Sciences, and Social Sciences, Thirteenth Edition
• ISBN-13: 978-0321869838
• Comment: Use this ISBN if you are purchasing online; this is likely to be the least expensive, provided that you do not wish to use MyMathLab for independent study.
• Author: R. Barnett
• Title: Calculus for Business, Economics, Life Sciences, and Social Sciences (Custom Edition for Ventura College), Thirteenth Edition
• ISBN-13: 978-1323051573
• Comment: This is one of the packages available in the VC bookstore; as we will not be using MyMathLab, you do not need the MyMathLab bundle unless you want to use it on your own for extra study.

If you use the Kindle or other digital version, you will want to be able to refer to the information during class, so be sure you own a compatible device (laptop, mobile phone, or e-reader) that you are willing and able to bring to class with you every day.

Recommended study-guide problems

(These are sample exam-like problems for practice purposes; do not turn in with your homework)

Exam date is Wed. 8 March
(For students with minimal study time)
Page 175 (Review Exercises): 4–10 ALL; 25; 26 (use difference quotient); 27 (use any method); 28 (use difference quotient); 29–31 ODD (use the properties from section 2.5); 39; 40; 43–49 ODD (use the properties from section 2.5 to obtain needed derivatives); 55–67 ODD; 73–81 ODD; 91; 97
(For students with additional study time)
The above plus
Page 175 (Review Exercises): 11–24 ALL; 30 (use any method); 44–48 EVEN (use the properties from section 2.5 to obtain needed derivatives); 56–68 EVEN; 72–82 EVEN
Unassigned problems from the ranges of the homework assignments from sections 2.1 through 2.5
2.6 Differentials 9–19 ODD; 27–31 ODD; 33(A)(C); 35(A)(C); 45; 47; 51; 54 (answers to #54: 2.6 and 1.3)
There are two ways to find the exact change $\Delta y$: either $\Delta y = f\left( {{x_2}} \right) - f\left( {{x_1}} \right)$ or $\Delta y = f\left( {x + \Delta x} \right) - f\left( x \right)$; use whichever form best matches the information given in the problem. The estimated change is given by $dy = f'\left(x\right)dx$; if $dx$ is not given, calculate it from $dx = x_{2}-x_{1}$.
2.7 Marginal Analysis in Business and Economics 9–25 EOO (all odds recommended if time permits); 33; 37; 49 ("break-even" means that profit is zero, or $P\left(x\right) = 0$)
These are really just more differential problems, so the formulas from section 2.6 still work; however, when "marginal" is used, the implied value of the run is $dx = 1$. So if a problem asks "what is the cost of the 26th widget", then assume that $x_{1} = 25$, $x_{2} = 26$, and $dx = x_{2}-x_{1}=1$.
3.1 The Constant $e$ and Continuous Compound Interest 13–21 ODD; 25–29 ODD; 33; 35; 41; 45; 47 42
3.2 Derivatives of Exponential and Logarithmic Functions 9–33 ODD; 41–53 EOO; 63; 65
3.3 Derivatives of Products and Quotients 9–33 ODD; 49–65 EOO; 77–89 EOO; 93

Typo warning: Problem 81 should read $\frac{{6\left( {\sqrt[3]{x}} \right)}}{{{x^2} - 3}}$ not $\frac{{\left( {{6^3}} \right)\sqrt x }}{{{x^2} - 3}}$
3.4 The Chain Rule 17–65 EOO; 95(A); 98
3.5 Implicit Differentiation 13–29 ODD; 35; 37; 51; 53 (for the last two problems, treat $p$ as if it were the dependent variable $y$) 48
3.6 Related Rates 9–25 ODD
3.7 Elasticity of Demand (No assignment)
4.1 First Derivative and Graphs 33–45 ODD; 85; 87; 89; 95; 97

Notes:
1. A "partition number" is a value of $x$ for which either $f'\left( x \right) = 0$ or $f'\left( x \right)$ does not exist. A "critical number" is any partition number which is also in the domain of $f\left( x \right)$. So every critical number is a partition number, but not every partition number is a critical number. For example, consider $f\left( x \right) = x - 2\ln{x}$. The domain is $\left( {0,\;\infty } \right)$ because the natural logarithm is not defined for $x \leq 0$. The derivative is $f'\left( x \right) = \frac{x-2}{x}$, so the partition numbers are $x=0$ (because $f'\left( x \right)$ is undefined there) and $x=2$ (because $f'\left( x \right) = 0$ there). But only $x=2$ is a critical number, because $x=0$ is not an element of the domain of $f\left( x \right)$.
2. Every extremum (local minimum or maximum) of a function occurs at a critical number, but not every critical number is an extremum. There must be a sign change in $f'\left( x \right)$ at the critical number for that location to be an extremum. For example, $f\left( x \right) = x^3$ has a critical number at $x=0$, but it is not an extremum because $f'\left( x \right) = 3x^2$ is positive on both the left and right sides of $x=0$.
3. For the word problems, note that the increasing/decreasing intervals do not extend to infinity. Only evaluate increasing/decreasing behavior on the given domains. In #95, for example, only evaluate increasing/decreasing behavior on $\left( {0,\;150 } \right)$.
4.2 Second Derivative and Graphs 33; 37; 49; 53; 57; 61; 65; 69; 87; 91; 93 (graphs are optional)
4.3 L'Hopital's Rule (No assignment)
4.4 Curve-Sketching Techniques (No assignment)
4.5 Absolute Maxima and Minima (No assignment)
4.6 Optimization 9–45 EOO

6.2 Applications in Business and Economics 25; 27; 41
6.3 Integration by Parts 9; 11; 15–27 ODD; 37–57 ODD; 63; 67 (review 6.2); 69 (review 6.1)
(Warning: Some of these problems may be solved by the method of $u$-substitution, as in section 5.2; you may need to experiment with both of these methods. For the problems involving integration by parts, multiple applications of the method may be necessary for #37 and some of the others)
38; 46; 56

## Course Handouts and Study Aids

The documents listed below are available for viewing or download. The list below provides links to download free software to read the file formats of the various documents.

• PDF (Adobe® Acrobat Reader™) is the best format to use if you want to print on paper (for example, to replace a lost copy).
• HTML files are not, for the most part, printer-friendly; this is the best format for on-screen reading, and if you can read these words, you already have the software!
• DOC and DOCX files are in the native Microsoft® Word format; if you do not have Word, use this Word Viewer from the Microsoft web site (this software can display Word files, but cannot modify them).
• PPT files are PowerPoint® presentations; if you do not have PowerPoint, use this PowerPoint Viewer, again from the Microsoft web site.

## Will You Succeed or Fail in Mathematics?

This checklist is adapted from a handout prepared by math and philosophy instructor Steve Thomassin. It will allow you to compare your approach to a mathematics course to the approaches taken by successful … and unsuccessful … students.

Overview: This table lists typical attributes of successful and unsuccessful mathematics students. It contains three columns. First row: Column headers. Second and subsequent rows: Student attributes. Details: The first row is the table header, with column headings describing the data listed in the main body of the table. The second and subsequent rows describe specific attributes that contribute to success or failure. Column one of these rows specifies whether the attribute is related to attitude, class work, homework, or getting help. Column two of these rows contains attributes of successful students. Column three of these rows contains attributes of unsuccessful students.
Attribute Type Predictor of Success Predictor of Failure
Attitude Focus on things that are under your control. Blame things that are out of your control (the text, the instructor, or "the system") for your difficulties.
Be optimistic. Believe that you can do it. Be pessimistic. Convince yourself that you will fail.
Be positive. Find ways to make math interesting and fun. Be negative. Find ways to make math dull and painful.
Be open. See the uses, power, patterns, and magic of mathematics. Be closed. Blind yourself to math's uses and its practical and esthetic value.
Be practical. Make yourself aware of the doors that passing each math class opens to you. Be impractical. Ignore the doors that open when you pass a math class.
Class Work Attend every class. Aim for perfect attendance, even if you already know it all. Be absent often. Dig a hole so deep that you cannot climb out except by dropping the course.
Be focused. Concentrate on the math topic at hand. Be mentally elsewhere. Daydream. Talk. Distract and annoy neighboring students.
Take good notes. Solve problems along with the instructor. Avoid participating in the discussion. Just watch the instructor.
Be inquisitive. Ask questions so that the instructor knows what you would like to learn more about. Be uninterested. Make the instructor guess what it is that you might be confused about.
Homework Be regular. Always do at least some homework before the next class, and finish by the due date. Be sporadic. Do homework only when it easily fits your schedule.
Invest time. Spend double to triple the amount of in-class time. Invest little time. Spend less time doing homework than you spend in class.
Review notes; read text; do all assigned problems (maybe even more), and check the answers. Ignore notes and text explanations; try a few problems, and don't bother checking to see if they are right.
Getting Help When needed, take advantage of all opportunities: study groups, tutors, instructor office hours. Even when lost, never seek assistance.
