Special Features

o View Your Grades

Grades for this semester and previous semesters are available on the OCCC MineOnline system. Here’s a procedure for viewing them.

o Guide to Academic Costume and Music

Since graduation is just around the corner, it’s time to develop some skill at “reading” the academic robes and to get some background on the academic song “Gaudeamus Igitur.” Here’s an academic costume and music annotated webography to get you started.

o Prof. Oates’s Spring 2012 Teaching and Office Hours Schedule

Here’s my OCCC schedule for the Spring 2012 term.

o Math Help (Other Subjects, Too!)

Lots of help for math and other subjects is available at KhanAcademy.org and free-ed.net. Give them a try.

o Scale of the Universe

Here’s a literally mind expanding website where you’d do well to spend some time.

o Prof. Oates’s Pics

2012-04-29, Amy's Third Birthday Party (new), 2012-03-28, Amy and Papa Give the SMO Pass Another Workout (pics with *videos* and *slideshow* function at Chuck's Picasaweb Site ) (recent), 2012-03-26, Investigatin' Patterns at Science Museum Oklahoma (SMO) (pics with *videos* and *slideshow* function at Chuck's Picasaweb Site ), 2012-03-xx, The Tee-shirt Series, 2012-03-17, Amy, Off to a St. Patrick's Day Visit, 2012-03-15, Spring Flowers at Louie's Restaurant, 2012-03-14, Amy and Papa Space Out at SMO on PiDay, 2012-03-09, Amy, Carri and Papa Visit SMO at "Tornado Alley" Introduction, 2012-03-05, Amy and Papa Visit SNOMNH, 2012-02-26, Feedin’ the Geese, Spring Hath Sprung, 2012-02-06, Amy and Papa at SNOMNH—New Guinea Exhibit, 2012-01-29, Marcie’s Baby Shower. More pics are available far below, near the bottom of this very long main page. Also, a preview slideshow of the latest pics is now near the very bottom of the page.

o Blog Moved

Prof. Oates’s blog, formerly located at chuxstuff.blogspot.com, can now be found at ProfOates.blogspot.com.

o View the Near-beta Version of Prof. Oates’s Math Info Site

You can view and comment on Prof. Oates's (New) Math Information Site, still under construction. Your constructive comments and problem reports will be much appreciated.

If you need to construct a website in a hurry, consider wordpress.com for the task. I reconstructed the website you are reading on the WordPress’s blog site in about 12 hours total (so far).

o Top Ten Lists for ChuckOates.com (updated 2010-01-29, reformatted 2010-02-12)

Top Ten Lists of most frequently accessed pages, images, and blog entries on this website are now available.

o How NOT to Analyze Data

"Global Warming Stopped in 1998" Oh, really? Here's a classic case of 1) playing fast and loose with data, cherry picking a short segment while ignoring the bigger picture and 2) complete failure to understand the complexity of the system that's being discussed. At best, it's a manifestation of ignorance; at worst, it's a classic propaganda technique. Have a look at the big picture here . Be careful not to make such an error yourself or unwittingly spread the results of someone else’s erroneous analysis. A statistics course [find “Statistics”] is a useful prevention for some of these kinds of errors. So is the study of propaganda techniques.

o Personal Items Section Moved

The Personal Items section is now at the bottom of this very long main page.

OCCC Course Information

o Math General Education Courses and Course Precedence Diagram

A summary of the OCCC general education math courses is available here.

- Help for the TI-83/84/84+ calculator is available at www.occc.edu/college_algebra .

- Some algebra help is available at KhanAcademy.org and free-ed.net.

Module 1: Graphs, Functions, and Models

- Instructions for the linear regression project are available page by page at these locations:

for Excel 1997-2003: Page 1, Page 2, Page 3, and Page 4. -- borrowed from Math for Health Careers
for Excel 2007: Linear Regression Project, Excel 2007. -– also borrowed from Math for HC, requires Adobe Acrobat Reader available here.

Module 2: More on Functions

- Composition of Functions Examples

Examples of composition of functions, for example (g◦f)(x), (f◦g)(x), are presented here.

- Summary of Stretching, Shrinking, Translation, and Reflection

Here’s a summary of the information on page 212 in the text: Stretch, Shrink, Translate, Reflect.

- Set Theory

If you’d like a brief introduction to sets and their operations, i.e., unions, intersections, complements, etc., there is a brief introduction available in this Wikipedia article. The material in the Basic Operations section is particularly useful.

Module 3:

Sketching Quadratic Functions Example

Module 4: Exponentials and Logs

- Exponential regressions and three-data-point quadratic fits

Instructions for performing exponential regressions on the TI-84, as well as a solved problem that fits a quadratic equation to three data points here.

- Applications of exponential functions: musical scales, equal tempered vs. just toned scales

Have you ever wondered how the frequencies for musical notes are determined? It turns out that an exponential function, specifically 2^n/12, is heavily involved in the modern 12-note chromatic equal tempered scale, successor to the old just-tone scale used before the time of J.S. Bach. Here’s a link to a discussion of the equal tempered musical scale and practical piano tuning, as well as Prof. Oates’s Excel spreadsheet investigating some of the formulas presented in the above discussion.

Module 5: Systems of Equations and Matrices

Here’s draft document that describes tactics for solving IV drip rate problems. It’s in the “if-then-else-ish” English (also known as “pseudo-code”) that software people use to describe solution methods for problems. I hope it’ll help you organize your solution techniques for Chapter 10’s problems.

- Chapter 10 Problem Solutions

- Solution Guide for Module 4 Dosage Range and “Is it safe?” Problems

Some problems in the text and in Worksheet 32 are dosage range or “Is it safe?” problems. Click this link to receive more information on dosage range/is-it-safe problems.

These problems require that two sets of calculations be made, one for the LOW LIMIT of the dosage range and one for the HIGH LIMIT. The ordered dose is then compared to these limits to see if it is either within limits and, therefore, SAFE or outside the limits and, therefore, potentially UNSAFE. Note that both the limits and the ordered amount must be in the same units.

- More Module 4 Problem Solutions

Here are some solved problems drawn from e-mail messages sent to APPM 1313 students recently. These should assist you in working the Module 4 homework.

. - Erratum, Module 4 Problem from the Textbook

The text’s incorrect answer to problem 3, page 216 is 9.7 mL/dose. The correct answer is 4.8 mL/dose.

The previous edition of the text had this same question, but in that edition the medication label displayed a concentration of 125 mg/5 mL; since the new label’s concentration is 250 mg/5 mL, the required number of mL is half that stated in the answer section.

Module 5

- Practice Test 5 is available here.

On the real Test 5, questions 12 – 16 will be replaced by dilution problems similar to those on Worksheets 40 and 41.

- Help for Module 5 Dilution Problems

When synthesizing (building) dilution setups, you’ll need this write-up on Chuck's Quick and Dirty Dilution Technique, CQDDT.

Here’s a copy of an e-mail response I sent to a student requesting help on Module 5 dilution problems. You should read and try to understand the material in Worksheets 36 through 39 before reading this document.

- Help for Linear Equations, y = mx + b

Material describing properties of linear equations is available here.

- Worksheets for Module 5 are available using the links that follow.

Module 5 Worksheets: WS 34, WS 35, WS 36, WS 37, WS 38, WS 39, WS 40, WS 41, WS 47, and WS 48.

Landscape-oriented Versions of Worksheets: WS 38L and WS 39L

Note that we did the significant digits worksheets (42-46) earlier in the course.

- Excel 2007 Version of Materials for Computer Projects 1, 2, 3 and 4 are available below.

Computer Projects v. 2007: Instruction Packet Front Sides, Instruction Packet Back Sides

- Excel 1997-2003 Version of Materials for Computer Projects 1, 2, 3 and 4 are available below, page by page.

Computer Projects v. 1997-2003: Page 1, Page 2, Page 3, Page 4, Page 5, Page 6, Page 7, Page 8, Page 9, Page 10, Page 11, Page 12, Page 13, and Page 14.
