Solids_with_known_cross_sections

Let's leverage the definite integral to find volumes of figures where we know what their cross sections look like. It is surprisingly fun.

Shell_method

Shell method offers us another way of calculating the volume of solids of revolution. Some solids are more easily found with the shell method.

Washer_method

Washer method is an extension of the Disk method for finding the volumes of more elaborate solids of revolution.

Disk_method

You know how to use definite integrals to find areas under curves. We now take that idea for "spin" by thinking about the volumes of things created when you rotate functions around various lines.
