Algebra and Trigonometry: Graphing and Data Analysis

*Designed for the Precalculus course covering Algebra and Trigonometry. This text covers right angle trigonometry first and then develops the unit circle approach. This text requires student use of graphing calculators or a computer based software program. For schools who wish to cover unit circle first, please see "Precalculus: Graphing and Data Analysis". * The goal of this text is to provide a solid mathematical foundation via visualization of real world data. Technology is used as a tool to solve problems, motivate concepts, explore and preview mathematical concepts and to find curves of best fit to the data. Most mathematical concepts are developed and illustrated both algebraically and graphically - with the more intuitive and appropriate method presented first.
