Hello,
If you just want to have a traditionalform output, you can do it like
this :
MakeBoxes[Log[a_], TraditionalForm] := RowBox[{"ln(", a, ")"}]
Afterwards, all the traditionalform ouptuts will write ln(x) instead of
Log[x]...
But I'm not sure that it is a good idea... Maybe we better just get used
to the Mathematica habits!
Regards
F.Jaccard

The natural logarithm function in "traditional form" in Mathematica
(version 6.0.2.0)
Log[x]//TraditionalForm
log(x)
This is "not a bug but a feature", but in mathematics the natural
logarithm
is just ln(x) or even ln x.
The true traditional notation use log for decimal logarithm, ln for
natural
logarithm, lb for binary logarithm, and
log_{b}x for logarithm with base b. Unfortunatelly in most computer
programs (see FORTRAN) LOG
stands for natural logarithm (an exception is Pascal).
Nevertheless, how to force to use ln(x) instead log(x) ?
The brute way is use /.Log->ln//TraditionalForm.
Is any more elegant way to do this?
