Synopses & Reviews
PRECALCULUS prepares learners for calculus and the rigors of that course, having been written by teachers who have taught the courses and seen where learners need help--and where other texts have come up short. The text features precise definitions and exposition, carefully crafted pedagogy, and a strong emphasis on algebraic, transcendental, and trigonometric functions. To show readers how important and relevant precalculus topics are to their future coursework, an optional Looking Ahead to Calculus feature appears in each chapter. The varied examples and exercises include many that encourage readers to use and understand graphs, as opposed to simply draw them, providing additional sound preparation for calculus.
Review
Neal, Gustafson, and Hughes have produced a very thorough textbookthat covers the subjects that high school students will need to prepare for courses in Calculus. The volume moves from introducingbasic concepts like equations, graphs, and polynomials, on through to trigonometry, vectors, and even linear algebra, concluding withintroductions to sequences, series, and probability theory. The final chapter is available only online and is an actual introductionto Calculus itself. The book makes use of a system of special boxes throughout the text with names like Looking ahead to Calculus, Accenton Technology, and Careers and Mathematics. These contain brief introductions to the relevancy of the material to each topic. Thereare also "Strategy Boxes" that offer hints to the student as to how to attack a problem. The book is completely in color and containsnumerous high quality color graphs and illustrations. On the front and back flaps of the book as well as the subsequent page areglossaries of recurring formulas, definitions, and rules such as the trigonometric identities, factoring, quadratics, and rules of exponents.Annotation ©2014 Ringgold, Inc., Portland, OR (protoview.com)
About the Author
Karla Neal received two degrees in mathematics from Louisiana State University and has been an instructor in the department of Mathematics for 31 years. During that time, she has served as the coordinator for College Trigonometry for more than 15 years. She has received three campus-wide teaching awards, and has served as a faculty advisor for several Christian campus organizations. Karla is an avid fan of the LSU Tigers. When she is not on campus, she is very active in her church, Healing Place Church in Baton Rouge, and can often be found on the golf course. At home, there are two dogs, Winston and Josie, waiting patiently. R. David Gustafson is Professor Emeritus of Mathematics at Rock Valley College in Illinois and has also taught extensively at Rockford College and Beloit College. He is coauthor of several best-selling mathematics textbooks, including Gustafson/Frisk/Hughes' COLLEGE ALGEBRA, Gustafson/Karr/Massey's BEGINNING ALGEBRA, INTERMEDIATE ALGEBRA, BEGINNING AND INTERMEDIATE ALGEBRA, BEGINNING AND INTERMEDIATE ALGEBRA: A COMBINED APPROACH, and the Tussy/Gustafson and Tussy/Gustafson/Koenig developmental mathematics series. His numerous professional honors include Rock Valley Teacher of the Year and Rockford's Outstanding Educator of the Year. He has been very active in AMATYC as a Midwest Vice-president and has been President of IMACC, AMATYC's Illinois affiliate. He earned a Master of Arts from Rockford College in Illinois, as well as a Master of Science from Northern Illinois University. Jeff Hughes has taught the college algebra course continually for the past 20 years, and his firsthand experience with students lends itself to the innovative ideas he has brought to the text. He has led the way for the addition of the new features and the revised content in COLLEGE ALGEBRA, 10E. He teaches at Hinds Community College in Mississippi.
