  • This calculus video tutorial explains how to use the disk method and the washer method to calculate the volume of a solid when the region enclosed by the curves are rotated around the x axis, y axis, and non axis or another line parallel to the x or y axis. This video contains plenty of examples and practice problems for you to work on. It shows you how to set up and evaluate the definite integral. Techniques include expanding a binomial expression and basic integration rules.

    correct me if I'm wrong, but isn't the washer method the one that involves two functions on the graph (ex: y = 2x, y = 5x + 1)? If so, I didn't notice the washer method in this video, only the disc method.

      You are right but they are basically the same thing anyway. As you said, the washer method involves two functions and you apply the disc method twice and substract the little one fromm the bigger one.

      @@paulagaona9622 nope they aren't.
      washer method covers rings, disc method covers ,well discs and shell method covers both.

    Why go to class when you can just look up the topic of the lesson on the OCT channel? Fr saved me on multiple tests because of the simplistic and easy to understand explanations.

    I'm kind of sad that you're not uploading the full video again, for free... I would be very delighted to cover the harder problems in the latter part of your videos, but i guess you also need to monetize your hardwork. Anyways it's still a big help ty
