## Preface

The 20th century Dutch artist Maurits Cornelis Escher was a master printmaker, whose works were heavily infused with ideas from mathematics. This textbook is intended to support a mathematics course at the level of college algebra, with topics taken from the mathematics implied by Escher's artwork.

This textbook is intended to be supplemented by one or more printed books about Escher. In particular, Visions of Symmetry contains essential complementary material on Escher's life and mathematical approach to symmetry, and Magic of M.C. Escher is an excellent art book that provides a much better view of Escher's artwork and technique. It is important to remember that artwork viewed on the web is usually small, grainy, and has poor color reproduction.

Throughout the text you will find Explorations, which are short investigative projects to be done in groups in a class setting. Explorations are intended to introduce material in a way that motivates and prepares the student for the more rigorous approach in the body of this text.
