INTRODUCTION with these applications requires that the teacher and the learner examine the mathematical principles behind why and how a concept is applied. content The content in this reference guide is based on over forty mathematical con- cepts that are studied in different levels of high school mathematics. For exam- ple, linear functions are typically learned in algebra and are continually used beyond calculus. Each of the concepts is listed alphabetically and can be read independently. This format has been selected for pragmatic purposes, so that the applications can be used efficiently. Consequently, we occasionally synthesize concepts, such as referring to slope and derivative as rates, or cross-reference topics because some applications are based on related or multiple concepts. The ideas presented in this book are not a comprehensive account of high school mathematics nor do they represent every possible application. We do not feel that every mathematical principle taught in a high school curriculum has a realistic application. We do feel there are situations where it is necessary to explore some mathematics that may not be applied. For example, the study of angles formed by parallel lines does not have many realistic applications, but the concepts can be used to introduce similarity, a topic with many useful applica- tions. In addition, the concepts presented here do not introduce every application of high school mathematics. Our intent is to promote applications about mathe- matical concepts that are commonly studied in high school mathematics, even though there are additional interesting connections to other concepts that may not have as much emphasis in a school’s curriculum. Furthermore, we simply cannot be aware of all of the applications that have realistic connections to the concepts we have listed. If you have any additional ideas, please share them with us by sending an email to The depth of description of an application varies within each concept. Some- times an application will be described in the form of a story, and other times it will be described in a few sentences to avoid redundancy with a similar analysis in another section. Sometimes we will just point in the direction of an important application. Sometimes we will provide a historical, rather than contemporary, application to show the genesis of a mathematical concept. The amount of math- ematics described in each of the sections varies, depending on the context and complexity of the situation. We would much rather provide a flavor of how mathematics is used than go into detail for every application. In fact, many appli- cations discussed in this book are based on simplified conditions, even though the real world often has unusual limitations, constraints, or peculiarities. For example, we neglect weather conditions when studying the motion of a baseball. Furthermore, we approximate the shapes of objects, such as assuming that the earth is a perfect sphere. Simplified situations are used in this reference guide in order to provide general principles in a concise manner so that the concepts can be understood by a high school student.
