My mistake. Are we talking about 0/0 ? I was thinking 0/x. 0/0 is as Phil says, unknown until you differentiate.
1 is a nice answer as it is a nice average for a slope. Slope is a positive fraction, and 1 is the middle number out of the positive fractions. Not the mathematical way I know, but it just struck me while reading Phil's email and I think it's quite a cute way to explain it :) Hen On Wed, 13 Aug 2003, Phil Steitz wrote: > Age old question.
