Precalculus is intended for college-level Precalculus students. Since Precalculus courses vary from one institution to the next, we have attempted to meet the needs of as broad an audience as possible, including all of the content that might be covered in any particular course. The result is a comprehensive book that covers more ground than an instructor could likely cover in a typical one- or two-semester course; but instructors should find, almost without fail, that the topics they wish to include in their syllabus are covered in the text. Many chapters of Openstax Precalculus are suitable for other freshman and sophomore math courses such as College Algebra and Trigonometry; however, instructors of those courses might need to supplement or adjust the material. Openstax will also be releasing a College Algebra and Trigonometry title tailored to the particular scope, sequence, and pedagogy of those courses.
Principles of Microeconomics covers the scope and sequence for a one-semester economics course. The text also includes many current examples, including; the Keystone Pipeline, Occupy Wall Street, and debates over the minimum wage.
The pedagogical choices, chapter arrangements, and learning objective fulfillment were developed and vetted with feedback from educators dedicated to the project. The outcome is a balanced approach to economics and to the theory and application of economics concepts. Current events are treated in a politically-balanced way, as well.
Principles of Macroeconomics covers the scope and sequence for a one-semester economics course. The text also includes many current examples, including: the housing bubble and housing crisis, Zimbabwe’s hyperinflation, global unemployment, and the appointment of the United States’ first female Federal Reserve chair, Janet Yellen.
The pedagogical choices, chapter arrangements, and learning objective fulfillment were developed and vetted with feedback from educators dedicated to the project. The outcome is a balanced approach to economics, to both Keynesian and classical views, and to the theory and application of economics concepts. Current events are treated in a politically-balanced way, as well.
Introductory Statistics is intended for the one-semester introduction to statistics course for students who are not mathematics or engineering majors. It focuses on the interpretation of statistical results, especially in real world settings, and assumes that students have an understanding of intermediate algebra. In addition to end of section practice and homework sets, examples of each topic are explained step-by-step throughout the text and followed by a Try It problem that is designed as extra practice for students. This book also includes collaborative exercises and statistics labs designed to give students the opportunity to work together and explore key concepts. To support today’s student in understanding technology, this book features TI 83, 83+, 84, or 84+ calculator instructions at strategic points throughout. While the book has been built so that each chapter builds on the previous, it can be rearranged to accommodate any instructor’s particular needs.
