Rather than simply finding the area beneath one curve, in this lesson we wish to find the area bounded by two curves. Let's begin with a few warm-up exercises as a preview of how we will set up some of these problems. No calculus, all algebra. Duration: 5:39

Remember when we first approximated the area beneath a curve by partitioning the region into rectangles? We will do the same thing here to develop a Riemann sum. After taking the limit as n approaches ∞, we arrive at the definite integral representing the area between the two graphs. Duration: 8:27

Now that we have a complete understanding of how use a representative rectangle to generate first a Riemann sum and then a definite integral to find the area between two curves, let's model that process on Example 1. Duration: 5:16

Example 2 gives us another opportunity to compute the area of the region imprisoned between two curves over a given interval. Duration: 3:46
