Cylindrical shell vs washer method
As we know the washer method and shell method both apply in the calculations. But the uses of both methods are vital and beneficial method of integration. Sometimes, it is best to use the washer method in case of finding volume of solid revolutions and sometimes the shell method works more … See more Suppose that we have a region R, bounded between the curves y=f(x) and y=g(x) from x = a to x = b as shown in a figure. If we take this region and revolve it around the y axis, we obtain the following solid of revolution … See more For understanding the washer method, we will recall the washer method about the y-axis. Suppose that we have a region bounded between … See more Let R be the region bounded in the first quadrant by the curve y = 1-√x, on the x-axis and the y-axis.

WebThe Washer Method Some solids of revolution have cavities in the middle; they are not solid all the way to the axis of revolution. Sometimes, this is just a result of the way the region of revolution is shaped with respect to the axis of revolution.

WebSep 21, 2024 · Method 1: Disk (washer) Method. Remember, the disk and washer method are the same thing. In the disk method, we visualize stacked circles (or pancakes, as I like to say). The washer method is the same stacked pancakes with holes (like washers or donuts). I like to complete every problem with the same thought process. WebWhen using the shell method, if we rotate around a horizontal axis we use x as the variable of integration. 3) The two methods are based on different formulae. The washer method uses the formula for volume of a washer. π[(r outer) 2 – (r inner) 2] Δ x (or Δ y) The shell method uses the formula for volume of a shell. 2πrh Δ x (or Δ y)
