This book, Conceptual Math and Beyond (Precalculus), was published by Brilliant Creations Publishing, Inc., to serve as a basic textbook for Precalculus under the Science, Technology, Engineering and Mathematics (STEM) strand.
The subject Precalculus deals with concepts and problems involving conic sections, systems of nonlinear equations, series and mathematical induction, circular and trigonometric functions, trigonometric identities, and polar coordinate system.
To address this need, the book has been subdivided into ten chapters:
Chapter 1: Exploring Circles
Chapter 2: Exploring the Parabola
Chapter 3: Exploring the Ellipse
Chapter 4: Exploring the Hyperbola
Chapter 5: Understanding Systems of Nonlinear Equations
Chapter 6: Exploring Series and Mathematical Induction
Chapter 7: Exploring the Unit Circle
Chapter 8: Exploring the Trigonometric Identities
Chapter 9: Exploring Inverse Trigonometric Functions and Trigonometric Equations
Chapter 10: Exploring the Polar Coordinate System
Practical applications have been used in the presentation of the lessons, and the concepts are presented in the manner that the students would easily understand the computations. Examples are provided to guide the students in the step-by-step approach to problem solving.
Serving as a prerequisite subject for Basic Calculus, it is sincerely hoped that the learners and teachers will find this book, Conceptual Mathematics and Beyond (Precalculus) very helpful, and thus apply the lessons learned whether for personal or for future use in their chosen careers.
