Thanks for the detailed response, Simon. Please understand that I'm
not being critical of Sage-- quite the contrary, I'm excited about
what it might offer me once I master it.
I think you touch on one key to the problem-- I'm not a
mathematician,
Another solution, different from the previous ones is to convert sws
file to pdf using sws2tex - http://bitbucket.org/whuss/sws2tex/
It should be trivial to hack the python or TeX code to remove the
content of input cells.
example of the output is http://user.mendelu.cz/marik/sage/as.pdf

I screened all of the offered documents from the sgaemath-page to find a
list of the offered standard-functions - no success! May be there is a
table or list about that but I just could not find it? Screening the
index is one possibility, but does not make me really happy.
Tnx BB

Hi,
Do you mean something like these:
http://wiki.sagemath.org/quickref
?
Otherwise, the reference manual http://sagemath.org/doc/reference/ has a
full list.

Hi!
Question out of ignorance: What do you mean by a 'standard function'?
Is it calculus stuff such as sin and cos, or do you mean Python
functions?
If it is the latter, you may get a list of all callable objects in the
global name space by
sage: F = [f for f in globals().values() if

I would write it as
filter(callable, globals().values())

Is there any way to check whether a symbolic expression is a
derivative. Like,
isinstance(diff(f(x),x),what to put?)
gives True
and
isinstance(f(x),what to put?)
gives false, assuming f is not a derivative itself.

No, it's not a bug since the operator is the function f:
sage: f.operator()

Thank you!
Is amazing how flexible the notebook is, since
it uses HTML instead of ReST... (yes, I know, it's flexible enough to
support cross-site scripting attacks too).
That's the same as with other CAS.
I've officially given up on ever getting VirtualBox to work properly
on my netbook (I'm pretty sure it's just a memory issue), so I'd like
to go back to the last VMware version (4.1.2, I guess).
I can find where to find the source code for the old versions, but
I've looked all over sagemath.org
Hi,
Coincidentally, I gave up on using virtualbox for sage-windows. The
next version will be vmware based. Expect this early next week.
