There's probably a better way, but this works:
sage: f = function('hello',x)
sage: f._f._name
'hello'
(That's just what f._repr_() uses.)

Hi all:
How do you retrieve the name of a callable symbolic function as a
string? For instance, suppose you have
sage: f= function('hello',x)
and you want to retrieve 'hello' from f.
sage: str(f)
'\n hello(x)'
followed by stripping away the extra characters

How do I get the pretty print. I am using CentOS and Firefox.

On two different computers running Ubuntu 9.04, I downloaded and built
from source sage 3.4.1. I also downloaded scipy using the synaptic
package manager. I am under the impression that python and scipy in
sage lead completely separate lives from python and scipy outside
sage. In normal python
Hello,
just trying to follow examples of http://www.sagemath.org/library/crypto.pdf
Exercise 8.5 solution: page nr 124 (or 127 for file) has suspicious
code
sage: E := RSACryptosystem(128)
sage: m = E.encoding(’The dog ate my lunch.’); m
first of all typo of assignment (seems like in Pascal)
Too tricky, but maybe this helps:
sage: c,x = var("c,x")
sage: y = function('y',x)
sage: soln = desolve(diff(y,x)+sin(x)*y^6==0,y); soln
1/(5*y(x)^5) == c - cos(x)
sage: soln.subs(x = pi)
1/(5*y(pi)^5) == c + 1
sage: ssoln = soln.__repr__(); ssoln
'1/(5*y(x)^5) == c - cos(x)'
sage: ssoln = ssoln.

why are debs not updated?
I don't know much about them, and as I remember main pac
Hello, I just want to test, if I can do with my students in computer
lab what they usualy do on the paper
1. find general solution
2. substitute from initail conditions
3. find c
4. use this c in general solution
I agree that this may be strange to do this in the case, we have a
command for solv
Yes, I recompiled it and it works. It took 7 hours on the P4.

I don't know if you are asking about how to use ICs in
desolve or if you are asking about how to do substitutions.
Anyway, I get this:
sage: y=function('y',x)
sage: desolve(diff(y,x)+sin(x)*y^6==0,y)
1/(5*y(x)^5) == c - cos(x)
sage: desolve(diff(y,x)+sin(x)*y^6==0,y,[pi,9])
1/(5*y(x)^5) == (-295
Dear memebers of SAGE-support
I wonder if it is possible to substitute initial conditions into an
equation produced by desolve. I tried something like
y=function('y',x)
desolve(diff(y,x)+sin(x)*y^6==0,y)
sol({x:pi,y:9})
and got
1/(5*y(pi)^5) == c + 1
but I would like to see
1/(5*9^5) == c

Hello,
I have sage on fresh Ubuntu jaunty,
SAGE Version 3.0.5, Release Date: 2008-07-11
but when I use notebook, I get unnecessary output
and line endings of it seem like have encoding problems..

Dear SAGE experts,
from the output of desolve?? command I understand that desolve call
maxima and ode2 to solve ordinary differential equations.
1. How can I get the access to method variable?
commands
maxima("ode2('diff(y,x)=x^6*cos(y),y,x)")
maxima('method')
give the answer "separable", but
Hi,
I saw in trac that the ticket about my problem to start Sage in a
Debian Lenny 64bit is closed since GAP was downgraded.
I thought Sage-3.4.1 should now works on my server... but it still
doesn't. And the problem is still the same. When I run sage for the
first time, I got:

This is because the interactive shell has a preparser. H
