When I type in
plot(x^(1/3), -1, 1)
Sage balks at me. Apparantly it doesn't understand that the cube root of a
negative number is well defined. Is this a bug? I found no easy way to get
around it.

Hi all,
I am wondering how to make some computations with rather specific

Mathematically, I have the following field:

Thanks. I am really glad you're trying things out. This use case hadn't

hi,
Is there any way to remove the installed package(not the native one,
optionally installed only).
i used ./sage -f url to install the packages, but now i no longer need
some packages.
Cheers

You are right, Maple plots x^(1/3) only for positive x. As a side

Hi all,
I am legally blind, legally deaf, some limited finger mobility, and
some learning disabilities too (all from Rubella). I enjoy mathematics
and programming but due to my limited income Mathematica is just out
of my reach even for the Home edition. A friend told me about SAGE.
Cool!

I've had to deal with adapt_to_callable a bit, and I too would greatly

One thing that I think should be handled in adapt_to_callable, or

allowed to explicitly specify variables in plot ranges (thi

Another quick option: is there a way to get a listing of all the
commands/functions/keywords used in SAGE (the top level not at the
source code level)? Can that listing be done within context of topical
arrangement?? Inside SAGE in a cell or exported as a text file?
Thanks.

Is there a Sage equivalent to Maple's "nops" command, which counts the
number of operands in an expression? In particular, is there a
command which returns the number of terms of something like
expand((1+x+1/x)^10) ?
Thanks,
Alasdair

That works well, but what about when the expression is multivariate,
such as:
expand((1+x+1/y)^10)
It would be nice to have a general command to count the number of
summands in such an expression.
Thanks,

There might be a better way of doing this, but one way to get the
docstrings that show up with ? is:
q = globals().keys()
q.sort()
docstrings = [eval(x).__doc__ for x in q]
It really depends on what exactly you want to do though - it may be
more helpful to use a dictionary where the keys are the

Yep, I think there are ways of making this nicer.

There is also a **kwds's notation, which you should learn about.
