How do you find the volume of a function that rotates over the X-axis?
How do you find the volume of a function that rotates over the X-axis? The Disk Method V=πb∫a[f(x)]2dx. The cross section perpendicular to the axis of revolution has the form of a disk of radius R=f(x). Similarly, we can find the volume of the solid when the region is bounded by the curve x=f(y) and […]
