Staff Review
The theory behind integrals and areas under curves is explained again, and this is applied to situations in which you would like to find the area between curves instead of the area under a curve. Several different example problems are done, showing how to think of the problems geometrically, how to set them up, and how to compute the areas. Some of the areas are able to be computed by splitting them up into multiple integrals, some are easier by integrating with respect to x, and some integrating with respect to y. A good variety of examples are provided.
