520			_a"This revised edition of Precalculus presents additional software applications that integrate the utilization of technology as additional support to address the needs of the present generation of learners in this modern and fast-changing world. The authors believe that teaching and learning mathematics can be made much more interesting and exploratory by optimizing the potential of technology, as teachers, as well as students, have access to instructional technology including hardware and other devices with mathematical software, online calculators, and other applications which are useful in in graphing equations, checking solutions, and verifying answers to problems. The study of mathematics has become very important in daily life because of its wide-ranging applications. For this reason, the authors have come up with this rich material, Precalculus, designed for Grade 11 students to serve as their foundation prerequisite for calculus and other higher mathematics subjects. This covers topics on analytic geometry, series and sequences, and trigonometry, all of which are prescribed by the Department of Education (DepEd) for Precalculus. This book has an easy-to-understand approach and step-by-step solutions to problems for a thorough understanding of the topics. This also discusses the application of precalculus concepts and theories in engineering, architecture, economics, navigation, and other related fields. This book includes sufficient examples and illustrations to expedite teaching-learning processes in every topic. At the end of each chapter, a Chapter Review summarizes concepts and formulas discussed within the chapter. Exercises are also provided in different forms, namely, It's Your Turn!, How Clear is the Lesson to You?, and Chapter Test, to assess the students' performance and to measure their learning progress as preparation for higher-level competencies. The authors wish to acknowledge their families for the inspiration, and friends for the motivation, in writing this book." —Preface
