disk method 和 washer method (就是shell method 或 cylinder method), 是计算 revolving volume 的两种最常用的方法。disk method = 圆盘法 将旋转体按垂直于旋转轴(revolving axis), 切割成一片一片的薄片，薄片的体积为 dv = πy²dx = π[f(x)]²dx (revolving about x axis...

CALCULUS AB VOLUME – REVIEW (Disk Method, Washer Method, Shells Method, Cross Sections)SHOW ALL WORK IN YOUR NOTEBOOK The base region for all the following solids with known cross sections is the circle with equation: 229x y +=. Find the volume in each case if the cross sections...
The washer method is very similar to the disk method, but there is a second function creating space between the area that will be revolved and the axis of rotation. In this formula, both functions are squared; then, the inner function squared is subtracted from the outer function squared. ...
As with the disk method, we can also apply the washer method to solids of revolution that result from revolving a region around the yy-axis. In this case, the following rule applies.The Washer Method for Solids of Revolution around the yy-axis Suppose u(y)u(y) and v(y)v(y) are ...
2 b a V y d x Since we will be using the disk method to rotate shapes about other lines besides the x-axis, we will not have this formula on the formula quizzes. 2 b a V x d y A shape rotated about the y-axis would be: The region between the curve , and the y-axis is...
Stoppers ; cork, treating.-In making cork washers or discs for bottle closures, cork bark is cut up into a series of thin layers, the thickness of each layer being preferably less than one half the thickness of the final washer or disc. The layers are then built up into a pile, some...

The accelerator includes a first tank for accelerating charged particles at a first velocity to a seco... DA Swenson...
10. Use the disk/washer OR the shell method to find the volumes of the solids generated by revolving the region bounded by the graphs of the equations about the given line. Include a sketch of the graph of the regions. List which method ...
[′disk ‚spriŋ] (mechanical engineering) A mechanical spring that consists of a disk or washer supported by one force (distributed by a suitable chuck or holder) at the periphery and by an opposing force on the center or hub of the disk. ...
