How to Use This Book

You can use this book any way you please. If you choose to read it cover to cover while lounging on a sunny beach in Kauai, that's fine with me. More likely, you'll want to keep it within arm's reach while you toil away in your dimly-lit cubicle.

Due to the nature of the subject matter, the chapter order is often immaterial. Most readers will probably skip around, picking up useful tidbits here and there. The material contains many examples, designed to help you identify a relevant formula quickly. If you're faced with a challenging task, you may want to check the index first to see whether the book specifically addresses your problem.
