Preface INTEGRATED MATHEMATICS: COURSE II, Second Edition, is a thorough revision of a textbook that has been a leader in presenting high school mathematics in a contemporary, integrated manner. Over the last decade, this integrated approach has undergone further changes and refinements. Amsco s Second Edition reflects these developments. The Amsco book parallels the integrated approach to the teaching of high school mathematics that is being promoted by the National Council of Teachers of Mathematics (NCTM) in its STANDARDS FOR SCHOOL MATHEMATICS. Moreover, the Amsco book implements many of the suggestions set forth in the NCTM Standards, which are the acknowledged guidelines for achieving a higher level of excellence in the study of mathematics. In this new edition, which fully satisfies the requirements of the revised New York State Syllabus: ~ Problem solving has been expanded by (1) adding nonroutine prob- lems for selected topics and to Chapter Reviews, and (2) providing, in the Teacher s Manual, Bonus questions for each chapter. ~ Integration of Geometry, Logic, Algebra, and other branches of mathematics, for which the First Edition was well known, has been broadened by the inclusion of new topics and the earlier introduction of selected concepts. ~ Algebraic skills from Course I have been maintained, strengthened, and expanded as a bridge to the requirements of Course III. Note that many of these skills, newly highlighted in the revised Syllabus, already appear in the First Edition of the AMSCO text. ~ Enrichment has been extended by (1) increasing the number of challenging exercises, (2) introducing a variety of optional topics, and (3) adding to the Teacher s Manual more thought-provoking aspects of topics in the text, and supplementary material that reflects current thinking in mathematics education. ~ Hands-on activities have been included in the Teacher s Manual to promote understanding through discovery. iii
