Calculus: A Complete Course, 10th Edition, contains 21 chapters, P and 1-20, plus 6 Appendices. It covers the material usually encountered in a three- to five-semester real variable calculus program, involving real-valued functions of a single real variable (differential calculus in Chapters 1-4 and integral calculus in Chapters 5-8), as well as vector valued functions of a single real variable (covered in Chapter 12), real-valued functions of several real variables (in Chapters 13-15), and vector-valued functions of several real variables (in Chapters 16-18). Chapter 9 concerns sequences and series, and its position is rather arbitrary."
