Re: [sage-support] Re: Jacobi sn
Hi
I can also do this (Note the only change I - %i):
sage: maxima(jacobi_sn(1.2 + 3.7081493546*I, 0.500))
jacobi_sn(3.7081493546*I+1.2,0.5)
sage: maxima(jacobi_sn(1.2 + 3.7081493546*%i, 0.500))

Numerical evaluation for this function is done by the _evalf_()
function defined on line 489 of sage/functions/special.py. The last
line of that function is:
return parent(maxima(%s, numer%self._maxima_init_evaled_(*args)))
Here is what happens:
sage: maxima(jacobi_sn(1.2000 + 3.7081493546027438*I,
0.5), numer)
jacobi_sn(3.7081493546027438*I+1.2,0.5)
Trying to convert this to an element of RR, or whatever the chosen
parent for the numerical evaluation is, calls this function again.
The problem is with the conversion of the argument to maxima in the
_maxima_init_evaled_ function. I will open a ticket and try to provide
a patch today. Gotta run now.

[sage-support] Re: output from sage to file
I understood. Then next question. I build sage from source. In terminal. $ sage No command 'sage' found, did you mean: Command 'osage' from package 'graphviz' (main) Command 'save' from package 'atfs' (universe) Command 'page' from package 'tcllib' (universe) sage: command not found Best regards, Aleksandr -- You received this message because you are subscribed to the Google Groups sage-support group.

Re: [sage-support] Re: output from sage to file
Hi Your sage installation seems to be in /home/toivo/sage/. This is normally called SAGE_ROOT, which is a bash variable. You can set the command sage to be an alias for /home/toivo/sage/sage like this alias sage='/home/toivo/sage/sage' and you can make this permanent for all new terminals you open by adding that line to your /home/toivo/.bashrc file, the configuration file for bash.
