OCCC Course Information

O College Algebra, Spring 2010

Math 1513-024 College Algebra (T-Th 1:30 – 2:50 p.m., MB 3N5)

Materials Requirements

- The text book is OPTIONAL, but highly recommended; however, the MyMathLab package is REQUIRED.

- Also, a three-ring notebook with at least 1 ½ inch spine and divider pages is also required. They’re available in office supply departments for a few dollars.

Course Overview Materials

- The Spring 2010 section syllabus and tentative schedule is now available for

MATH 1513-024, T-Th 1:30 – 2:50 p.m., MB 3N5.

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

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 HC
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

- 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.

- Below are some answers to questions I’ve received about Pretest 2. (Fall 2008)

There’s an error in the answer to the pretest’s question 18. The correct answer is [6, ∞). The answer that’s given the pretest’s answer section is the domain of (g ◦ f), not (f ◦ g). Sorry. :^(

In pretest problem 19, what’s required is the algebraic checks that follow.  1)  Replace x with -x and if the function remains unchanged, it's symmetric about the y-axis.  2)  Replace y with -y and if the function remains unchanged, it's symmetric about the x-axis.  3)  Replace both x with -x and y with -y and if the function remains unchanged, it's symmetric about the origin.  A function can have any combination of these three properties, including all the properties or none of the properties. The text has a good explanation on page 200. See the purple-shaded box and the example on that page. I’ll allow more room for your answer on any similar problem on the actual test.

In pretest problem 20, I'm looking for the even and odd checking that's defined in the purple-shaded box at the top of page 202 in the text and carried out in the example at the bottom of the page.  Recall that we developed these tests informally in class using f(x) = x³ and g(x) = x² as examples.

Module 5: 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.

Module 6: Systems of Equations and Matrices

Project: Non-Linear Regression

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.

- 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
