WebThe disc method is used when the area extends under the curve to the axis of rotation, whereas the washer method is used when the area extends from one curve to another curve. Basically, you use the disc method when there's only one equation. You use the washer method when there are two or more curves and you're looking at an area … WebAnd so what we're going to do is attempt to do this using, I guess you'd call it the washer method which is a variant of the disk method. So let's construct a washer. So let's look at a given x. So let's say an x right over here. So let's say that we're at an x right over there. And what we're going to do is we're going to rotate this region. WebDisk/Washer and Shell Methods A solid of revolution is a solid swept out by rotating a plane area around some straight line (the axis of revolution). Two common methods for nding the volume of a solid of revolution are the (cross sectional) disk method and the (layers) of shell method of integration.
