You have been blessed with an above-average ability in mathematics; otherwise, you wouldn't be taking this class. This textbook will take you from your present understanding of mathematics to the point where you should be prepared for calculus. Trigonometry is the common thread that ties the material in this book together. You will see trigonometry in almost every chapter. Two other key concepts are functions and graphing. These ideas are fundamental to your future mathematics classes. You will also study some new concepts, including sequences and series, matrices, and calculus. You will notice a more theoretical approach in this text, and at this point in your mathematical maturity you should try to understand this theory. Through mathematics you are studying laws that God has established. You are learning more about the nature of God through this study and, we trust, becoming more Christ-like as godly characteristics are reflected through you. - Introduction.
