Calculus is the study of the infinite and since much of secondary mathematics is designed to prepare one for the study of calculus, wrestling with the ideas of the infinite, even if informally, is extremely important for a student's mathematical development. That is the purpose of this book.
Among the first to discuss these ideas was the Greek philosopher / mathematician Zeno, and not long after him, Archimedes came the closest to discovering Calculus without the tools of modern mathematics. Though none of Zeno's actual writings survive, Aristotle recorded accounts of Zeno's thoughts on the infinite, time and space in what have come to be known as Zeno's Paradoxes. One of those specifically involves the idea of a race in which a slower runner is given a head start and investigates the possibilities of the faster runner 'catching up'. This has come to be known as 'Achilles and the Tortoise'. These characters are our hosts as we use the modern software, Geometry Expressions, to investigate Archimedes methods, ideas of the infinite, and Zeno's Paradoxes in an introduction to Calculus, without using Calculus.

The purpose of this book is to use Geometry Expressions software in order to facilitate and enhance the calculus syllabus by allowing students to ground calculus concepts in a geometric way. The 29 student explorations in this book cover the major topics of a standard course of calculus, and are completed with the help of the constraint-based dynamic software package, Geometry Expressions. Using Geometry Expressions in learning calculus, students have the opportunity to develop general investigation skills, make connections between geometric and algebraic representations of major calculus ideas, interpret analytic problems visually and geometric problems algebraically, and develop facility with using a computer to prove general mathematics statements. Geometry Expressions enables more extensive calculus investigation than is possible in a traditional course of calculus.

The typical student complaint about secondary mathematics is that it appears to have no practical application. The design and implementation of crop circles using center pivot irrigation provides us with an excellent example to see mathematics in action. By investigating these crop circles the lessons in this book utilize images from Google Earth, and a lighthearted scenario of a discussion between a farmer and a mathematician to introduce important mathematical concepts that are appropriate and adaptable for students in a range of courses from Pre-Algebra, Algebra, and Geometry, up through and including Calculus.

This is Mr. Ottman's second book about a corny farmer and his mathematician friend. Our farmer uses a Center Pivot Irrigation System - those long stretches of wheeled scaffolding, sometimes up to a half-mile in length, rotating around a fixed point attached to his water source. This presents real world geometry problems concerning how to fit a circular or semi-circular irrigated plot into a polygonal (usually rectangular, sometimes triangular or even trapezoidal) field.
As in the first book, we demonstrate to the student that Mathematics is not just for calculating the price of produce in the grocery store. Here we have a fresh batch of examples of mathematics in action using our symbolic geometry software, Geometry Expressions, with images from Google Earth.
So join the Farmer and his mathematical instructor, Sophie, as they fly over Texas, investigating interesting geometrical ideas and stumbling over important mathematical concepts. The content is appropriate and adaptable for students in a range of courses from Algebra and Geometry up through and including Calculus.

We wrote this book with the hope to help teachers to engage their students in learning geometry and encourage them in their development of logical thinking. This book offers 43 interesting geometry problems that resulted from a collaboration of Russian and American educators. They reflect the content of the standard high school curriculum. Altogether these problems demonstrate the most important methods of geometry. The unique features of these problems include use of symbolic geometry software, Geometry Expressions. Each problem includes student black line master and detailed teacher notes with solutions, proofs, and steps for working with Geometry Expressions.

This book comprises 101 examples of the use of Geometry Expressions in a variety of settings. In some cases, we give a simple model with little explanation. In other cases, there is some exposition backed up by Geometry Expressions models. Some examples make use of an algebra system in addition to Geometry Expressions, while many use Geometry Expressions stand-alone. Together, we hope, they give an indication of what the system can do, and provide a starting point for the reader to pursue his own discoveries.

The goal of this book is to show you what you can do with the conic section capabilities of Geometry Expressions 2.0. The goal is not to teach you conic sections, though you might learn some interesting or arcane facts about them on the way. Neither is the goal to teach you how to use Geometry Expressions, though you might pick up a few pointers en route.

Geometry Expressions provides a playground where students can discover their own mathematics. They will begin to see mathematics as something that is created, not just a set of facts made up long ago. Once students take ownership of their mathematics, they will be more apt to "work productively and reflectively, with the skilled guidance of their teachers."
The units presented in this book are a jumping-off point for using Geometry Expressions in the classroom. Use the units to gauge the potential of this powerful software, and as a guide to applying Geometry Expressions in your own classroom. We trust that you will enjoy using the units and the software.

This unit is designed to familiarize students with the ideas of how various functions can be transformed, and the effect those transformations have on equations, graphs, and contextual situations. It specifically investigates three basic function types: those with parent functions y=x2, y=1/x, and y=sin(x). These function families were chosen because they are simple enough for students to readily understand, and also sophisticated enough to clearly demonstrate the effects of dilations and translations. The skills and principles to be learned apply to virtually all function families, and will give a solid foundation for more advanced studies in functions.

From the back cover: "Ian Sheppard's book is based around a set of activities using the computer program Geometry Expressions. The author's passion to provide students with engaging learning opportunities is evident throughout. The activities embrace investigative approaches and seek to enhance student learning through discovery and the use of computer technology. Geometry Expressions has two features that add to the genre of dynamic interactive geometry software, constraints and symbolics. The activities and approach are designed to emphasize these additional features, constraints as an intuitive way to construct diagrams and symbolics as a link between algebra and geometry."

From the back cover: Our goal was to use Geometry Expressions to develop a set of problems for second year algebra and/or precalculus courses addressing the topics of geometric transformations of functions and optimization. In this volume you will find eight interactive problems with different levels of difficulty. In each problem the main focus is on the development of the students' ability to recognize and make connections using multiple representations of the same object, such as geometric shape and function. By connecting geometric and algebraic representations the student develops a more thorough understanding of the problem.
