I reverted your edits at Defined and undefined and Indeterminate form. At the first one, 0^0 is undefined indeed, and not only by "shortest-sighted of authors", but simply because that expression can take any value. At Indeterminate form, you switched from ln to log in denoting the natural log, that is incorrect math notation. Oleg Alexandrov (talk) 16:26, 19 December 2006 (UTC)

There's nothing incorrect about using "log" for natural logarithm. It has long been a commonplace usage among mathematicians. Longer than "ln". Michael Hardy 20:27, 19 December 2006 (UTC)

Indeed, and still far, far more common than "ln" amongst mathematicians as well. Also 0^0 is almost never left undefined anymore, it's pretty much always defined as 1 by discrete mathematicians and analysts alike. Leaving it undefined has very few benefits, and just makes various things more awkward to express.
