linear regression project are available page by page at these locations:

for Excel
2007: Linear Regression Project, Excel 2007. -– borrowed from Math
for HC, requires Adobe Acrobat Reader available here.

Module 2: More on Functions

Functions Examples

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

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:

Functions using a Formula from Analytic Geometry

Sketching Quadratic Functions

Review questions for Module 4 for Fall 2012 and later can be found here (Adobe .pdf file). Answers for the review
questions are also available.

- 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. If you’d like *much* more information on the
physics of music, see this Michigan Tech web page.

linear equations in three unknowns on the TI 83/84
calculator.

Also, have a look at a couple of solved

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.

- 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.

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

Final Exam Review

- To review for the
final exam, just have a look at the material for each of the six modules,
above. The final exam questions will be
drawn from the module test questions.
Three or four questions from each module will appear on the final exam.

o Math for*Technical*** **Careers

- Here’s
some information on multiplying
binomial expressions in the Montessori style. (Top 5 Links: Number 1)

o Intro. to
Engineering, R.I.P.

- Just for old times’ sake,
here’s Practice Test #3 for OCCC’s late, great ENGR 1113,
Introduction to Engineering.

o View
Your Grades

- Grades for 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 Pharmacology Problems Solved by Dimensional Analysis

- Here’s
a link to some
pharmacology problems solved by dimensional analysis. This document attempts to show how
dimensional analysis is applied to problems closely related to those we do in
Math for Health Careers.

o Prof.
Oates’s Earlier Pics

These pictures have been moved to the CLOates Family Website.

o Blog Moved

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

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 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 Scale

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

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 National Weather Center Open
House

Here are a
number of pictures made at the NWC Open House, 4 November 2006, Norman, Oklahoma, USA.

o Severe Weather Footage, 5:30 p.m.
– 5:45 p.m., 10 May 2010

Here’s some
footage shot during the May
10 tornado outbreak.

o Lookin’ for a Career? Take the Path Less Traveled

Here are some thoughts
on careers for those considering their futures and, particularly, for those
graduating at various academic levels this spring: Lookin' for a Career?

o Images
from the News

Recent
oil drilling platform explosion images, Maps of the Gulf of
Mexico oil spill, Iceland's Eyjafjallajokull
volcano

o How to Tawk Texan

Texas:
it’s like a whole different ... planet.
Here’s your guide to Texas Ang-lish, so you can sound like a native when you
visit. For those who wish to take the
advanced course, The Unofficial Texas
Dictionary is also recommended, but it’s definitely second-semester stuff. You can find some colorful Texas expressions
at this
address, also. You’ll find a Texas
travel guide here. Don’t forget Texas’s most under-rated
attraction, the
Palo Duro Canyon, presented here in pictures and as a virtual tour.
