In this chapter we illustrate the definition of the definite integral of a realvalued function defined on a compact interval. We take a closer look at what kind of functions can be integrated and we develop a qualitative analysis of integrable functions, in a more precise way than is typical for calculus courses. The integral to be defined and studied here is now widely known as the Riemann integral.
