H. Freeman and Company New York This page intentionally left blank About the book We pay particular attention to the needs of the student, and provide many pedagogical features to make the learning process more enjoyable and effective. This section reviews these features. Paramount among them, though, is something that pervades the entire text: we try throughout to interpret the mathematical expressions, for mathematics is a language, and it is crucially important to be able to recognize what it is seeking to convey. We pay particular attention to the level at which we introduce information, the possibility of progressively deepening one’s understanding, and providing background information to support the development in the text. We are also very alert to the demands associated with problem solving, and provide a variety of helpful procedures. Molecular Interpretation icons Organizing the information Checklist of key ideas Checklist of key ideas We summarize the principal concepts introduced in each chapter as a checklist at the end of the chapter. We suggest checking off the box that precedes each entry when you feel confident about the topic. You should now be familiar with the following concepts.
