Shell method
Setting up the Integral
例题
Example 1:
Example 2:
Example 3: Computing volumes for solids of revolution using cylindrical shells利用柱壳法计算旋转体体积:
Shell method 柱壳法对于旋转固体体积的计算公式如下 Setting up the Integral • Keypoints: 1. When using cylindrical shells, you integrate with respect to the variable that is perpendicular to the axis of rotation.(使用柱壳法时可以相对于垂直于旋转轴的变量进行积分) 2. The integral can be set up as 2π ∫(a to b) r(x) h(x) dx or 2π ∫(c to d) r(y) h(y) dy , depending on the orientation. 例题 Example 1: Use the shell method to find the volume of the solid generated by revolving the shaded region about the y-axis. Limit is 0xpi Example 2:
Use the shell method to find the volume of the solid generated by revolving the shaded region about the x-axis. Example 3: Use the shell method to find the volume of the solid generated by revolving the region bounded by the given curves and lines about the y-axis.
