As part of the market-leading "Graphing Approach" Series by Larson, Hostetler, and Edwards, "Algebra and Trigonometry: A Graphing Approach," 4/e, provides both students and instructors with a sound mathematics course in an approachable, understandable format. The quality and quantity of the exercises, combined with interesting applications, cutting-edge design, and innovative resources, make teaching easier and help students succeed in mathematics. This edition, intended for algebra and trigonometry courses that require the use of a graphing calculator, includes a moderate review of algebra to help students entering the course with weak algebra skills.Accessibility to students is achieved through careful writing and design, including same-page examples and solutions, which maximize the readability of the text. Similarly, side-by-side solutions show algebraic, visual, and numeric representations of the mathematics to support students' various learning styles.The "Library of Functions" thread throughout the text provides a definition and list of characteristics for each elementary function and compares newly introduced functions to those already presented to increase students' understanding of these important concepts."Technology Support" notes provided at point-of-use throughout the text guide students to the "Technology Support Appendix," where they can learn how to use specific graphing calculator features to enhance their understanding of the concepts presented.Houghton Mifflin's "Eduspace" online classroom management tool offers instructors the option to assign homework and tests online, provides tutorial support for students needing additional help, and includes the ability tograde any of these assignments automatically.Larson, Ron is the author of 'Algebra and Trigonometry', published 2004 under ISBN 9780618394555 and ISBN 0618394559.
