Abstract:
This introductory chapter serves two overlapping purposes. First, it reminds the reader of much of the knowledge that is prerequisite for a course in single-variable calculus, particularly by presenting the notation and definitions that will be used later on. Since the material is familiar from high school, we will be fairly concise. Second, it provides a brief introduction to the axiomatic foundation of real numbers. Contrary to the usual high school approach, we start with a minimal set of properties that we accept axiomatically, and then show how we can prove, based on these, the set of known properties of real numbers. In particular, we introduce the concept of supremum, which is necessary at many critical points in the development of the theory, such as in the proof of Bolzano's theorem and in the definition of the integral.
