Algebra and Trigonometry 2e provides a comprehensive exploration of mathematical principles and meets scope and sequence requirements for a typical introductory algebra and trigonometry course. The modular approach and the richness of content ensure that the book addresses the needs of a variety of courses. Algebra and Trigonometry 2e offers a wealth of examples with detailed, conceptual explanations, building a strong foundation in the material before asking students to apply what they’ve learned.

The Algebra and Trigonometry 2e revision focused on improving relevance and representation as well as mathematical clarity and accuracy. Introductory narratives, examples, and problems were reviewed and revised using a diversity, equity, and inclusion framework. Many contexts, scenarios, and images have been changed to become even more relevant to students’ lives and interests. To maintain our commitment to accuracy and precision, examples, exercises, and solutions were reviewed by multiple faculty experts. All improvement suggestions and errata updates from the first edition were considered and unified across the different formats of the text.

In this free course, following our Principles of Microeconomics course, you'll continue to explore the economic way of thinking and the role incentives play in all our lives.

We'll cover fundamental macroeconomics questions such as: Why do some countries grow rich while others remain poor? How important is a country's banking system and what happened during the recent financial crisis? How did Zimbabwe end up with an inflation rate that rose into the quadrillions?

We'll also cover important topics like the Federal Reserve, monetary policy, fiscal policy, the Solow Growth Model, institutional analysis, the economics of ideas,and more.

This textbook concerns the wonderful world of macroeconomics, or economics on a very large scale, concerning national and international systems. It serves as an introduction to macroeconomics, and is primarily aimed at students in their final few years of secondary education, though it could also be used by interested students younger or older than that. See Intermediate Macroeconomic Theory for learning more advanced macroeconomics.;
;
Knowledge of microeconomics would be useful and preferred, but grasping overall concepts does not require an in depth previous knowledge. See Principles of Economics for a brief introduction to both microeconomics and macroeconomics and Principles of Microeconomics for learning introductory microeconomics.;

It is worth remembering that this textbook can be edited at any time, with the link at the top of this page. This is both good and bad - you yourself, having spotted a mistake or having noticed a poor definition, can correct it and should feel free to do so. The bad side is that anyone can edit it, so content may be inaccurate while the wikibook is in its infancy!

The textbook begins by looking at basic economic concepts and models, such as scarcity, choice, model-building, opportunity cost, production possibilities curves, comparative advantage, and supply and demand analysis. After a chapter exploring the relationships between markets and government, the text then delves into a rigorous analysis of the theory and practice of macroeconomics. Topics include the measurement of macroeconomic variables, macroeconomic models, and fiscal and monetary policy. The text emphasizes the connections between theory and policy in exploring the field of macroeconomics.
