Explorations in Precalculus Using the TI 83/83 Plus/84 Plus/86

This user-friendly workbook improves both student understanding and retention of algebra concepts through a series of activities and guided explorations using the graphing calculator. An ideal supplement for any college algebra or trigonometry course, EXPLORATIONS IN PRECALCULUS, Third Edition is a useful tool for integrating technology without sacrificing content. By clearly and succinctly teaching keystrokes, class time is devoted to investigations instead of how to use a graphing calculator. Arranged by topics, this workbook enables the instructor to assign the appropriate Explorations Unit(s) that correlate(s) with the topic under discussion in the classroom. The workbook has a flexible organization. Each unit has one or more prerequisite units that are required for student success in working the assigned unit. This allows the use of this ancillary text with any core course textbook. Charts that correlate the concepts from textbook sections with specific Explorations units are available in the Instructor Resources section of the Book Companion Web Site. The Companion Web Site can be accessed at http://mathematics.brookscole.com.

This supplemental workbook walks through the commands for performing computational tasks and graphing equations on Texas Instruments graphing calculators. The authors (Austin Peay State University) introduce the intersect and root/zero features to graphically solve linear, absolute value, quadratic, higher degree, and radical equations and inequalities. The third edition uses the TI-83/84 series as the base calculators and notes changes for the TI-86. Annotation ©2004 Book News, Inc., Portland, OR
