发帖数: 33 | 1 it all depends on the sequence of definitions. starting from
simple/'intuitive' ones, and build up all those craps. is PI
a intuitive one? not really, you need integretion to define it.
same for e. one approach is, define integral of 1/x as log(x),
then define log(e)=1. etc, etc. that's an intuitive appraoch.
you can't just start by defining a^x, it's not convincing. |
