College Algebra, Eleventh Edition, by Lial, Hornsby, Schneider, and Daniels, engages and supports students in the learning process by developing both the conceptual understanding and the analytical skills necessary for success in mathematics. With the Eleventh Edition, the authors recognize that students are learning in new ways, and that the classroom is evolving. The Lial team is now offering a new suite of resources to support today’s instructors and students.
New co-author Callie Daniels has experience in all classroom types including traditional, hybrid and online courses, which has driven the new MyMathLab features. For example, MyNotes
provide structure for student note-taking, and Interactive Chapter Summaries
allow students to quiz themselves in interactive examples on key vocabulary, symbols and concepts. Daniels’ experience, coupled with the long-time successful approach of the Lial series, has helped to more tightly integrate the text with online learning than ever before.

New and Updated Features
- The exercise sets offer many new and modified exercises, with updated real life data throughout.
- Numbered and Example references within the text are set in the same font as the figure and bold print for the example, helping visual learners identify and connect them.
- The “drop down” style is used whenever appropriate to distinguish between simplifying expressions and solving equations.
- Explanatory side comments are increased to guide students through the steps of simplifying and solving problems in the examples.
- In Chapter 1, the authors have re-written the introduction to the set of complex numbers and have included a new diagram illustrating the relationships among its subsets. They have also expanded the discussion of solving absolute value equations and inequalities.
- In Chapter 2, the authors have prepared new art for shrinking and stretching graphs, added new exercises on translations, and expanded the exercises involving the difference quotient to include additional greater degree functions.
- Chapter 3 has received a particularly extensive revision. The opening discussion of polynomial functions has been updated by providing a table of examples of polynomial functions (constant, linear, quadratic, cubic, quartic) and have identified the degree and leading coefficient. There is an increased emphasis on including all possibilities for positive, negative, and non-real complex zeros in a table format, with graphical representations used to illustrate them. There is now a new summary exercise set on solving both equations and inequalities (linear, quadratic, polynomial, rational, and miscellaneous).
- Chapter 4 includes more work with translations of exponential and logarithmic functions, and has additional examples and exercises on solving equations involving these functions.
- Chapter 5 includes the determinant theorems within the exposition, and contains new examples and exercises showing how they are used.
- Chapter 6 now includes more discussion on graphing ellipses and hyperbolas centered away from the origin.
- The discussion of binomial probability in Chapter 7 has been rewritten to provide more detail and clarity.

Marge Lial has always been 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, is now affiliated with American River College. Marge is an avid reader and traveler. Her travel experiences often find their way into her books as applications, exercise sets, and feature sets. She is particularly interested in archeology. Trips to various digs and ruin sites have produced 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). He has been a rabid 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.
David Schneider has taught mathematics at universities for over 34 years and has authored 36 books. He has an undergraduate degree in mathematics from Oberlin College and a PhD in mathematics from MIT. During most of his professional career, he was on the faculty of the University of Maryland--College Park. His hobbies include travel, dancing, bicycling, and hiking.
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 on an athletic scholarship, playing both basketball and tennis. While there, she earned a bachelor’s degree in Secondary Mathematics Education as well as the NAIA Academic All-American Award. 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 hobbies include watching her sons play sports, riding horses, fishing, shooting photographs, and playing guitar. 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.
