This site presents three textbooks. PreCalculus Essentials covers the essential material needed to prepare students for calculus. The purpose of this book is to strip away unnecessary topics and to allow for this course to be covered in a more manageable timeframe. PreCalculus Trigonometry covers the trigonometry needed to prepare students for a traditional calculus course. Rather than beginning the study of trigonometry with angles, this text begins with the wrapping function and the trigonometry of numbers. PreCalculus Trigonometry (Angle-First Approach) covers the trigonometry needed to prepare students for a traditional calculus course beginning with the trigonometric functions of angles. This book is similar to books with traditional approaches.
