The later is employed more deeply in some later chapters and at full strength in proper calculus courses. The aim of the first chapters is to provide a simple image-based preview or review of calculus. In it, dependence on symbols or algebra is kept to a minimum. The images may help readers to see and physically grasp the simplest slope-related ideas in calculus. The remaining chapters cover more topics see the table of contents.
Appendices present the most advanced topics.
Theorems in first courses on calculus are often stated without proof. The appendices state the theorems and give or indicate the proofs. This should provide a context for the decimal-free approach favored in advance calculus or modern mathematical analysis. This is a book which a student could begin reading in high school and continuing reading through further college math courses. Material elementary to advanced is covered.
