Simplify with factoring out. Apply the distributive property.

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. The integral symbol in the previous definition should look familiar. Although the notation for indefinite integrals may look similar to the notation for a definite integral, they are not the same. A definite integral is a number. An indefinite integral is a family of functions. Later in this chapter we examine how these concepts are related.

In the preceding section we defined the area under a curve in terms of Riemann sums:. However, this definition came with restrictions. We required f x f x to be continuous and nonnegative. 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. We lift the requirements that f x f x be continuous and nonnegative, and define the definite integral as follows.
