Hello,
suppose that we have the following expression :
(x**2+1)*(log(x+4)-7)
I would like to know that is a product and to have :
(x**2+1) and (log(x+4)-7).
Secundly, in
(log(x+4)-7)
I would like to have the fisrt level function log.
What do I mean by first level ? For example in
log(sin(x)-4)+exp(sin(tan(x)))
the fisrt lebvels functions are
log and exp
May be a way to have this would be to know that we have an addition and
to have the terms of an addition.
Any kind of infos are welcome.
Christophe
