Understanding the orientation of the element piece is important for setting up these integrals. For the disk/washer method the element piece must be perpendicular to the axis of revolution. For the shell method the element piece must be parallel to the axis of revolution. If the element piece is vertical then the integral must be in terms of x. If the element piece is horizontal then the integral must in terms of y. As for as which technique is better to use that really depends on the functions given. I would include the element pieces in the diagram and label the differentials, overall good video.

What is an element piece?
@DoctrinaMathVideos Жыл бұрын
@@gone3394 The element piece sometimes referred to as the "representative" piece (vertical or horizontal depending on the axis of revolution) that when rotated around the given axis of revolution produces a disk. The concept is that when we take the sum of these disks it gives us an approximate volume. If we want the exact volume then we take the limit of the sum as the number of elements increase. The key to setting up these volume problems is understanding the dynamics of the element piece which I introduce in my calculus 1 course since the element piece plays an important role in finding the area underneath the curve as well.
