Hi,
I would like to organize my worksheets, like having projects or
folders would be nice
20090917Homework#1< this would be
the folder name or the project name
Worksheet #1 drawingcurves < Worksheets in
above project
Workshee
just upgraded to 4.02 ...
I´m thinking what 4.02 really means because sage´s progress is really
fast, looking from user perspective Sage version numbers are changing
fast ? How far is this project ? Is there a way to show us users where
we currently are with current Sage version and what the cha
Thank you very much Stan, this was helpfull
I have more questions,
I get this message:
verbose 0 (3605: plot.py, _plot) WARNING: When plotting, failed to
evaluate function at 200 points.
verbose 0 (3605: plot.py, _plot) Last error message: ''
Why does it fail to evaluate ?

Thank you,
if I assign a value I lose symbolic expression ?
If I set GAMA=1 than gama in equation is not a letter/symbol of gama
but it is a number that was asigned to gama?
I though that I can keep the expression in symbolic notation and still
plot/calculate the equation.
So this means that the
var('G')
GAMA=var('gamma')
BETA=var('beta')
PSI=var('psi_c')
THETA=var('theta')
N=var('N')
MI=var('mu')
J1(x)=var('J_e1')
JR=var('J_R')
PI=var('pi')
GAMA==1
BETA==1
THETA==10
N==1000
MI==1
JR==0
PI==3
PSI==x
G = GAMA * (exp(PSI) + BETA*sqrt(THETA)*exp(PSI/THETA)) /
sqrt(2*PI*(N^2 * MI - 2*PSI))
Hi!
J is an equation with variables defined in ## my variables
What I want to do is plot the J versus x
x is a list of values lets say from -100 to 40
so how do I change from x=1 to x=[-100,..,40]
and fix this error:
"TypeError: cannot coerce type '' into a
SymbolicExpression."
I used list
PROBLEM SOLVED
Thank you Luis, William and all for your fast response.

apache is not installed
searched for other packages but cant find any similar to firewall,
network services intalled
I have these clients installed but thats shouldnt be a problem:
Also sage-3.02 gives me the same problem, that is, it cant not find
open port
I would like aslo ask if you guys run sage from KDE 3.5.9 or KDE 4 ?

I also tried:
./sage
notebook(port=8101)
tried also some other numbers 9000 7999 8500...80 50.. still the

Sage source was compiled as should without errors
Starting sage works fine
Running notebook() fails with error: RuntimeError: no available port
First it scans from port 8000 to 8050 and fails to find a free port
The rest i dont understand.
I tried to run as
