Algebra and Trigonometry: A Graphing Approach - Tapa blanda

Appropriate for freshman-/sophomore-level courses in Algebra and Trigonometry or Precalculus. This second in a series of three texts covers the traditional topics for Algebra and Trigonometry with a unique emphasis on concepts that are valuable to other courses or other applications, especially those that can be explored and illustrated on a graphics calculator. It de-emphasizes the more manipulative skills in favor of visualization, graphing, data analysis, and modeling of problems from the physical world.
