Yes, but I personally would drop the ftp and only use ssh/sftp and

Hi, I see that sage can call mathematica functions - I suppose that
only works if I have mathematica installed.
What I'm wondering is if I can import a mathmatica notebook into sage?
We used to have mathematica at my school and I remember using some very
nice mathematica notebooks by Jerry
sage: plot(x^2*log(x,2)-1, 0,2)
[nice plot so you can understand what is going on]
sage: find_root(x^2*log(x,2)-1,1, 2)
1.4142135623730951
Hi, I'm trying out SAGE for the first time, so I entered what you
suggested (see above).
Now, from the plot, it there seems to be no other roots between
Exactly, the function log base 2 of x is not defined at 0.
So, why won't sage return some sort of domain error?
I noticed something similar when I plotted (x^2-1)/(x-1) and got the
graph of x+1.
I was hoping for a removeable discontinuity to show in the graph!
IE a hole in y=x+1 at x=1.
TIA,
That's another issue: how do I know which package SAGE is using for a
particular task. You mention there may be a problem with maxima or
numpy, how are we to know?
