Mathematics in Action: An Introduction to Algebraic, Graphical, and Trigonometric Problem Solving gives you the math you encountered in high school or in previous courses, but in a new and meaningful way. An activity-based approach helps you achieve a higher level of conceptual learning, while developing a solid foundation of mathematical skills. The Mathematics in Action series is based on the authors' belief that students learn mathematics best by doing the math within a realistic context. From this perspective, they offer guided-discovery activities that help you to construct, reflect upon and apply mathematical concepts, deepening your conceptual understanding along the way. This active style of learning develops critical-thinking skills and mathematical literacy. The 6th Edition includes updated examples and activities for maximum interest and relevance.
