Section Summary: 6.2

  1. Definitions

  2. Theorems

    Make a list of all theorems (lemmas, corollaries) in the section (a few words each is fine). Summarize each one introduced in this section in your own words.

  3. Properties/Tricks/Hints/Etc.

    For a solid of revolution, the trick is to compute the radius r(x) (or, sometimes to ``confuse you'', r(y)), and rove over the appropriate axis.

  4. Summary

    This is a step up from computing areas: we're now computing volumes, by adding up little chunks of volume in the form A(x)dx (area times depth). The conceptual idea is the same, obviously, but we're in higher dimension.
