Editorial Reviews

The authors of this college-level text work from the premise that conceptual understanding and technical skills are inextricable. They emphasize a view of mathematics as a problem-solving art (rather than a collection of facts) that will help students succeed not only in subsequent math and science courses, but in the increasingly technology-oriented career world as well. Based on their own experiences in teaching algebra, trigonometry, and pre-calculus, they include elements such as progressive exercise sets, projects that students can work on alone or in groups, vignettes about interesting mathematicians and uses of math, and examples of real-world applications.
