disk method
[disk method|disk method] is a technique used to calculate volumes of solids of revolution by integrating with respect to y when the x-axis is the axis of revolution, and the function is expressed in terms of y.
Definition
disk method is a technique used to calculate volumes of solids of revolution by integrating with respect to y when the x-axis is the axis of revolution, and the function is expressed in terms of y.
Mechanism
disk method The disk method calculates volume by summing infinitesimal disks formed when a region rotates around the x-axis. Each disk's volume depends on the function's value at a point and the thickness of the slice.
Effects
disk method applies to solids of revolution created by revolving a region around the y-axis, resulting in washers. This method is used when the slices are disks, as seen in the slicing method for such solids.
