Preface

Teaching calculus for the first time can be a daunting task. Decisions must be made about how much time to spend on each topic, what points need special emphasis, what problems to assign for homework, etc. The purpose of this Instructor’s Manual is to provide guidance in such choices for instructors using Calculus, Early Transcendentals, 11th ed., by Howard Anton, Irl Bivens, and Stephen Davis. While the manual should especially be of help to first-time instructors and to first-time users of Calculus, it is hoped that even experienced instructors will find something of value here. The layout of the Instructor’s Manual is straightforward. Each section of Calculus is given a suggested time allocation and a teaching plan. The teaching plans range from short, for relatively straightforward sections, to lengthy, for sections that involve more sophisticated ideas. Each teaching plan also contains a bulleted list of key points to emphasize. Responses to questions posed in Margin or Technology Mastery Notes are included at the end of a section’s entry, followed by a sample homework assignment. (Of course the suggested teaching plans are precisely that, suggestions meant to provide guidance for instructors. The authors would be delighted to hear from instructors about what works, what doesn’t, what advice should be kept, and what should be changed or dropped.) The Instructor Companion Site for Calculus at www.wiley.com/college/anton provides additional resources for the instructor. There are slides that reproduce important figures from the text and sample exams for each chapter. This Instructor’s Manual points out what slides are available for each section. It is the authors’ hope that Calculus will help both instructors and their students to have an enjoyable and worthwhile teaching and learning experience. Please let us know how it goes.
