WebA washer is what is left when you cut a disk out of a disk. If your volume has a hole on axis, you need a washer. In your example, at y = 0 ,the region extends from x = 2 to x = 3, so is away from the center of revolution, the y axis, so you need washers.

WebSep 7, 2024 · We can use this method on the same kinds of solids as the disk method or the washer method; however, with the disk and washer methods, we integrate along the coordinate axis parallel to the axis of revolution. With the method of cylindrical shells, we integrate along the coordinate axis perpendicular to the axis of revolution. honda jazz 2015 bekas jakartaWebYou use the shell method when the axis you're rotating across is perpendicular to the axis you're integrating on. You use the disk/washer method when the axis you're rotating across is parallel to the axis you're integrating on. And if OP wants to understand why this is true, I strongly recommend drawing a typical slice of the region, and the ... fazer piadaWebThat depends on how you need to express the radius. For example, f (x) = x^2: Rotation around the x-axis will give us a radius equal to the fuction value, Rotation around the y-axis will give us a radius equal to the x-value, so we need an expression for the x-value. Thats why we do the inverse of the function. fazer pilhagemWebThe Disk/Washer Method: The Disk/Washer Method uses representative rectangles that are perpendicular to the axis of revolution.
