MyNotes for College Algebra and Trigonometry and Precalculus

Description

Content changes in the 7th Edition

• Chapter R has been expanded to include more of the basic concepts many students struggle with:
• It begins with new Section R.1 – Fractions, Decimals, and Percents. 
• Additional new topics have been inserted throughout the chapter, including operations with signed numbers (Section R.3), dividing a polynomial by a monomial (Section R.5), and factoring expressions with negative and rational exponents (Section R.6). 
• Topics throughout the chapter have been reorganized for improved flow.
• The exercise sets were a key focus of this revision, and Chapters 1 and 2 are among the chapters that have benefitted:
• Section 1.7 – Inequalities has new exercises on solving quadratic and rational inequalities, and Section 1.8 – Absolute Value Equations and Inequalities contains new exercises that involve the absolute value of a quadratic polynomial. 
• Section 2.3 – Functions has new exercises that use analytic methods to determine maximum and minimum values of a function, and Section 2.6 Graphs of Basic Functions contains new exercises and applications using the greatest integer function. 
• Section 2.4 – Linear Functions includes enhanced discussion of the average rate of change of a linear function. This topic is then related to the difference quotient and the average rate of change of a nonlinear function in Section 2.8 – Function Operations and Composition.
• Chapter 3 includes new Section 3.6 – Polynomial and Rational Inequalities. This section features a visual approach to solving such inequalities by interpreting the graphs of related functions. 
• Section 4.3 – Logarithmic Functions has new exercises that relate exponential and logarithmic functions as inverses. Chapter 6 includes additional exercises devoted to finding arc length and area of a sector (Section 6.1), as well as new applications of linear and angular speed (Section 6.2) and harmonic motion (Section 6.7).
• Proofs of identities in Chapter 7 now feature a drop-down style for increased clarity and student understanding. Based on reviewer requests, Section 7.7 – Equations Involving Inverse Trigonometric Functions includes new exercises in which solutions of inverse trigonometric equations are found.
• Section 8.4 – Algebraically Defined Vectors and the Dot Product has new exercises on finding the angle between two vectors, determining magnitude and direction angle for a vector, and identifying orthogonal vectors. Additionally, Chapter 8 contains new exercises requiring students to graph polar and parametric equations and give parametric representations of plane curves.
• Section 9.2 – Matrix Solution of Linear Systems now includes a new example and related exercises that use Gaussian elimination to solve linear systems of equation. Section 10.2 – Ellipses and Section 10.3 – Hyperbolas each include a new example and related exercises in which completing the square is used to find the standard form of an ellipse or a hyperbola.

Marge Lial (late) was always interested in math; it was her favorite subject in the first grade! Marge’s intense desire to educate both her students and herself has inspired the writing of numerous best-selling textbooks. Marge, who received Bachelor’s and Master’s degrees from California State University at Sacramento, was affiliated with American River College. An avid reader and traveler, her travel experiences often found their way into her books as applications, exercise sets, and feature sets. Her interest in archeology led to trips to various digs and ruin sites, producing some fascinating problems for her textbooks involving such topics as the building of Mayan pyramids and the acoustics of ancient ball courts in the Yucatan.

 

When John Hornsby enrolled as an undergraduate at Louisiana State University, he was uncertain whether he wanted to study mathematics education or journalism. His ultimate decision was to become a teacher, but after twenty-five years of teaching at the high school and university levels and fifteen years of writing mathematics textbooks, both of his goals have been realized. His love for both teaching and for mathematics is evident in his passion for working with students and fellow teachers as well. His specific professional interests are recreational mathematics, mathematics history, and incorporating graphing calculators into the curriculum. John’s personal life is busy as he devotes time to his family (wife Gwen, and sons Chris, Jack, and Josh), and has been an avid baseball fan all of his life. John’s other hobbies include numismatics (the study of coins) and record collecting. He loves the music of the 1960s and has an extensive collection of the recorded works of Frankie Valli and the Four Seasons.

 

A native Midwesterner, Terry McGinnis received her Bachelor’s of Science in Elementary Education with a concentration in Mathematics from Iowa State University. She has taught elementary and middle school mathematics, and developed and implemented the curriculum used with her students. Terry has been involved in college mathematics publishing for over 20 years, working with a variety of authors on textbooks in both developmental mathematics and precalculus. After working behind the scenes on many of the Lial/Hornsby textbooks and supplements for over 10 years, Terry joined Margaret Lial and John Hornsby in 2002 as coauthor of their developmental mathematics series. When not working, Terry enjoys spinning at a local health club, walking, and reading fiction. She is the devoted mother of two sons, Andrew and Tyler.

Callie Daniels has always had a passion for learning mathematics and brings that passion into the classroom with her students. She attended the University of the Ozarks where she earned a bachelor’s degree in Secondary Mathematics Education. She has two master’s degrees: one in Applied Mathematics and Statistics from the University of Missouri—Rolla, the second in Adult Education from the University of Missouri—St. Louis. Her professional interests include improving success in the community college mathematics sequence, using technology to enhance students’ understanding of mathematics, and creating materials that support classroom teaching and student understanding. She is able to pursue these interests as a contributor on the Lial Developmental Math series, and a co-author on the Precalculus series.
