What are the reasons for using washer meathod v.s cylindrical shells?

Cylindrical shells are much easier but there has to be some reason we can always use them

Hi carlosgrahm!

(i assume you're talking about finding a volume by integrating)

Sometimes one is easier, sometimes the other.

Do you have a specific problem in mind?
