Math V46, Fall 2018

Introduction and Announcements

[an error occurred while processing this directive]

Welcome to Math V46 (Applied Calculus) at Ventura College. Although Michael Bowen (email) is scheduled to teach this course during the fall 2018 term, an unexpected medical issue will require the appointment of a substitute instructor for at least the first several weeks of the semester. Your substitute is a fully qualified member of the Ventura College math faculty, and the duty of teaching this course will add to his/her already busy workload. Please take this into account, and consider volunteering to help your instructor with minor tasks such as (with the instructor's permission) offering to erase the whiteboards at the end of class meetings.

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.

Holidays

Classes at Ventura College will meet Monday through Thursday each week of the term, excepting only the dates listed below.

Please note that Columbus Day and Halloween Day are not Ventura College holidays.

Homework Club (Office Hours) During Finals Period

Final Examination

Place/date/time:  Room SCI-352, Monday 17 December 2018, 5:00 p.m.

Be sure that your big party to celebrate the end of finals occurs after the appropriate date. Requests for administration of early or late finals that require the instructor to reschedule his work or make a special trip to campus are subject to a deduction of points, regardless of the reason for the request.

Students with Disabilities

Students with disabilities who may need accommodations in this class are encouraged to contact the Educational Assistance Center (EAC) as soon as possible to ensure that such accommodations are implemented in a timely manner. Authorization, based on verification of disability, is required before any accommodation can be provided. You may contact the EAC by telephone at (805) 289‑6300, or visit the EAC office in the Administration (ADM) Building on campus.

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 $dx = x_{2}-x_{1}=1$. 		—

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 $\left( {0,\;150 } \right)$.
