Students are asked to answer questions and discover ideas throughout the body of the text, and to explore mathematical concepts in group lab projects. It employs a lively, fun writing style to communicate concepts to students in a way that can be easily understood. Graphing utilities are thoroughly integrated into the text, and their use is required. Users and reviewers have given this text high acclaim for its fresh applications, projects, and wonderful use of the discovery approach.
