The integral as represented in this chapter can be sometimes regarded as a mathematical modeling of the concept of area. However, once defined, the integral presents more than a tool for obtaining areas (or volumes), and calculation of integrals is quite popular, essential and helpful in all sciences, not just geometry. There are several definitions for the integral and in this chapter we follow most existing texts and introduce the most popular and applicable one: the Riemann integral.
