-> Right -- this is the *definition* of "divergent"!

OK, I'm learning something. Actually, this whole discussion has made me
feel the need to get out a few calculus books and read the chapters on
divergent/convergent series again. Last time I covered that material was
two summers ago, and I sure *thought* I understood it. I guess I've just
forgotten some of the particulars.

-> The best you can say is that
->
->       lim [a -> 0] <integral from -2 to -a> + <integral from a to 2>
->
-> is zero.

OK, this statement makes a great deal of sense to me. So that particular
limit above is zero, but the integral from 0 to 2 of 1/x is divergent.
OK. Thanks,

Sheila
