Cylindrical shells vs disk washer
Did you know?
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. WebNov 10, 2024 · In this section, we examine the method of cylindrical shells, the final method for finding the volume of a solid of revolution. We can use this method on the same kinds of solids as the disk method or …
