They cover the properties of the**real**numbers, sequences and series of**real**numbers, limits of functions, continuity, di erentiability, sequences and series of functions, and Riemann integration. They don’t include multi-variable calculus or contain any problem sets.1 Introduction We begin by discussing the motivation for
