解答: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...
7. Find the volume of the solid that lies between planes perpendicular to the x-axis at x = -1 and x = 1. The cross sections perpendicular to the x-axis between these planes are squares whose diagonals run from the semicircle 21y x =-- to the semicircle 21y x =-. 8. The base ...
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 ...
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...
