WebApr 13, 2024 · The Disk and Washer method is a calculus approach used to calculate the volume of a three-dimensional object, such as a cylinder or a cone. The method involves slicing the object into a series of discs, where each disc has an infinitesimal thickness. The discs’ volume is then accumulated through integration to find the object’s overall volume.

WebYou can always use either, the difference is that the washer method takes the cross-section of your final shape, then rotates it, while the disk method subtracts the entire volume of the shape enclosed by g (x) from the shape enclosed by f (x). WebThat depends on how you need to express the radius. For example, f (x) = x^2: Rotation around the x-axis will give us a radius equal to the fuction value, Rotation around the y-axis will give us a radius equal to the x-value, so we need an expression for the x-value. Thats why we do the inverse of the function.
