For courses in Algebra and Trigonometry.
Showing why math matters
Gary Rockswold doesn’t just mention real-world examples; he teaches mathematical concepts through those applications. For example, if we look at Facebook usage over time, what might that tell us about linear growth and predictions? In this way, students learn the concepts in the context of the world they know, which leads to better understanding and retention. From there, the author shows a connection between application, modeling, and visualization. Rockswold is known for presenting the concept of a function as a unifying theme, with an emphasis on the rule of four (verbal, graphical, numerical, and symbolic representations). The 6th Edition emphasizes conceptual understanding with new in-chapter features and assignment options, while at the same time providing tools to empower instructors to make their classroom more active through collaboration and group work.

About the Book
- See the Concept boxes are a hallmark feature, allowing students to make important connections by walking them through detailed visualizations. Students use graphs, tables, and diagrams to learn new concepts in a concise and efficient way. New to the 6th Edition, See the Concept Videos in MyLab Math bring key concepts to life and are assignable via assessment questions.
- New Exercise Types emphasize conceptual understanding and connections to calculus.
- Critical Thinking exercises ask students to take a mathematical concept a step further than what is discussed in the text. They challenge students to think beyond the pages of the book.
- Interpret & Analyze in Context exercises indicate where students need to interpret or analyze math used to describe real life.
- Checking Symbolic Skills exercises provide a preview into important topics that students will see again in calculus.
- 8 New Collaborative Activities, developed by the author as Appendix A, follow a project-based learning approach. Students actively explore real-world challenges and apply what they know to produce results that matter. Some activities focus on a specific concept while others span multiple concepts, requiring students to synthesize their knowledge.
