Ties together concepts using a functions approach

Known for their ability to connect with students, Sullivan and Sullivan focus on the fundamentals (preparing for class, practice with homework, reviewing key concepts), encouraging the conceptual understanding and mastery of basic skills needed for this and future courses. Part of the Concepts Through Functions Series, Precalculus: Concepts Through Functions, A Right Triangle Approach to Trigonometry, 4th Edition introduces functions at the start and maintains a continuous theme by introducing/developing a new function in every chapter. Graphing utility coverage is optional and can be included at the instructor's discretion.

Hallmark features of this title

  • Just-in-time review begins all sections to prepare students for the topics ahead.
  • Preparing for This Section lists previously learned concepts with page references that will be useful in the section ahead.
  • Now Work "Are You Prepared?" problems at the start of each exercise set help students check their preparedness for the section ahead.
  • Within each section, students get guidance to help them master material and develop problem-solving skills.
  • Assess Your Understanding at the end of every section offers a variety of problems to help students master skills.
  • DWR (Discussion, Writing and Research) problems are marked by an icon and red numbers. They support class discussion, verbalization of mathematical ideas, and writing and research projects.

New and updated features of this title

  • Updated Retain Your Knowledge  problems in the exercise set improve student recall of concepts learned earlier in the course. 
  • Updated graphing images  throughout each chapter show TI-84 Plus C and Desmos© screenshots. Using the graphing technology students are most familiar with, these images help students visualize concepts clearly and make stronger connections among equations, data and graphs in full color.
  • Revised definitions: 
    • Definitions have been reviewed and in a few cases updated for consistency with those presented in Calculus.
    • For example, in the definitions for increasing/decreasing functions, the word “open” has been deleted, allowing for functions to increase/decrease on any type of interval.
  • The objective “Find the Equation of a Line Given Two Points” in Chapter F, Section 3 has been moved after the objective “Identify the Slope and y-Intercept of a Line from Its Equation.” This allows the authors to express lines in slope-intercept form.

Features of MyLab Math for the 4th Edition

About our authors

Mike Sullivan recently retired as Professor of Mathematics at Chicago State University, having taught there for more than 30 years. He received his PhD in mathematics from Illinois Institute of Technology. He is a native of Chicago's South Side and currently resides in Oak Lawn, Illinois. Mike has 4 children; the 2 oldest have degrees in mathematics and assisted in proofing, checking examples and exercises, and writing solutions manuals for this project. His son Mike Sullivan, III co-authored the Sullivan Graphing with Data Analysis series as well as this series. Mike has authored or co-authored more than 10 books. He owns a travel agency and splits his time between a condo in Naples, Florida and a home in Oak Lawn, where he enjoys gardening. 

Michael Sullivan, III has training in mathematics, statistics and economics, with a varied teaching background that includes 27 years of instruction in both high school and college-level mathematics. He is currently a full-time professor of mathematics at Joliet Junior College. Michael has numerous textbooks in publication, including an Introductory Statistics series and a Precalculus series which he writes with his father, Michael Sullivan.

Michael believes that his experiences writing texts for college-level math and statistics courses give him a unique perspective as to where students are headed once they leave the developmental mathematics tract. This experience is reflected in the philosophy and presentation of his developmental text series. When not in the classroom or writing, Michael enjoys spending time with his 3 children, Michael, Kevin and Marissa, and playing golf. Now that his 2 sons are getting older, he has the opportunity to do both at the same time!
