A baffling climb-down from your previous position, but there is still the matter of the f'(0) when f(x)=x^3.

Yes, there is, John Gabriel. The fact that your tortured logic led you to this bizarre conclusion should have tipped you off that you had come to yet another dead end.

To the rational mind mind -- not to you, I'm afraid -- root 2 is an exact number.

See what I mean, folks?

How about the link to where you supposedly proved that 2+2=4, John Gabriel? Can't seem to find it at the moment? HA, HA, HA!
