Description
Technology and an investigative pedagogy are powerful tools for fostering in-depth understanding of mathematics concepts. Investigating College Algebra and Trigonometry with Technology presents the core concepts of College Algebra and Trigonometry within a technology-oriented, data-driven, applied framework that embraces investigative, collaborative learning. With this text, readers use graphing calculators, and optionally Microsoft? Excel and other technologies, to explore patterns and to make, test, and generalize conjectures. Most importantly, investigations--which engage readers in analysis of real-world data--promote collaboration and bring relevance to the mathematics students are learning.
