เนื้อหาย่อ : Preface This workbook is written for all those people who have tried problems in mathematics and felt the frustration of not obtaining the correct answer and not knowing where they went wrong. The workbook is structured on the belief that for most people mathematical techniques can only be learned through the use of examples and by independently working through problems and verifying the solutions. Readers who frst attempt the problems and then verify their answers will be able to master many of the mathematical methods needed to study intermediate and advanced undergraduate economics. Our goal is to provide the reader with the resources to become proficient in the mathematical analysis used in economics and business. The self-study approach of the workbook is well-suited to students taking courses in mathematical economics and economic theory and who wish to practise the techniques and methods learned in class. The workbook is also suitable for readers who may have previously learned the topics presented in the workbook but who need a review and practice. To help the reader, each chapter includes a review and introduction of the techniques used in the questions. The review is not a substitute to consulting the recommended texts because space limitations prevent the inclusion of almost all the theorems and proofs that underlie the techniques. We assume the reader has a basic knowledge of algebra and the rules of differentiation. As much as is possible, each chapter is structured to stand alone and, where necessary, references to other chapters are provided. In general, the questions are more dificult at the end than at the beginning of each chapter. We recommend, therefore, that the reader answer the lower numbered problems first so as to build the confidence and skills required for the more advanced questions. An important feature of the workbook is the emphasis on objective-based learning. To this end, we list the skills that will be acquired by correctly answering the questions given in each chapter. This provides a ready-made structure for self-learning and enables those readers who only wish to master sub-topics within a chapter to consult the relevant questions. We are grateful for financial support from the University of Ottawa in preparing the manuscript and for the facilities provided by the Norwegian School of Economics and Business Administration (NHH) and the Centre for Fisheries Economics during the summer of 1993. We also thank Stein Ivar Steinshamn of NHH and Chantale Lacasse and David Gray of the University of Ottawa for valuable comments on various chapters. We are especially indebted to Greg Flanagan of Mount Royal College for his encouragement and his many suggestions which have greatly improved the workbook. We would also like to thank students at the University of Ottawa for finding errors in the manuscript and for their many useful questions and comments. The efforts of Milan Jayasinghe and Sean Maguire who provided editorial assistance, Greg Flanagan who helped prepare the camera- ready copy, and Erin Flanagan who prepared the index are much appreciated.
