In the preceding section we defined the area under a curve in terms of Riemann sums:. However, this definition came with restrictions. In this section, we look at how to apply the concept of the area under the curve to a broader set of functions through the use of the definite integral. The definite integral generalizes the concept of the area under a curve.
