Step-by-Step

The Step-By-Step series originated in the fact that students simply don't need another textbook on Algebra, Calculus, etc. There are already wonderful textbooks on the market in almost every area of mathematics and science. What struggling students do need are more detailed, worked examples than are normally found in even the best textbooks. To solve this problem, every book in the Step-By-Step series contains hundreds of problems with both answers and detailed, worked solutions. In this volume, Step-By-Step: Precalculus, each of the major concepts in a standard Precalculus course is given its own section and problems. After a list of the problems for a concept, the answers are given so that students can compare their answers to the correct ones. Following the answers are detailed, worked solutions to each problem. The answers are given first because many students do not want to see a worked solution immediately upon finding that their answer is not the correct one. At the end of the book are two Final Exams that test whether or not the student has grasped all of the concepts in the book. Because students must be able to solve problems regardless of the order that they appear on their college/high school exams, the Finals are not in the same order as that given in the Table of Contents. The first Final Exam groups concepts that are similar (although not in the same order as presented in the book) and the second Final Exam completely randomizes the concepts and problems. As with every other problem in the Step-By-Step series, both answers and solutions to all Final Exam questions are included in the book.
