Other people can probably suggest other speedups, but one thing I
tried was adding:
var('x,y') #presumably you already did this at some point
npi = RDF(pi)
Having a numerical version of pi seems to speed it up by a factor of
20 or so.

It takes my machine around 10 seconds. I suppose it is the symbolic math?
f(x,y) = y^2*abs(3*exp(2*pi*i*(x+i*y))*3*exp(4*2*pi*i*(x+i*y)) +
8*exp(2*pi*i*(x+i*y

In case you want an icon - a small picture - for that "icon", I
thought about this today and i'll create some and a svg that is
suitable for kde

Sure. You can create a launcher or icon and just put "sage -notebook" as
the command. You might need to specify a path to Sage if it isn'
I am currently using Sage 4.2 in VirtualBox on windows XP. There is a
problem with symbolic determinants with 4.2 so I would like to switch
to 4.2.1 however none of the mirrors for VirtualBox have 4.2.1 only
4.2. Are there plans to post a 4.2.1 for VirtualBox? Thanks Mike

Hi.
I want to create an icon that will launch sage in it's notebook mode
immediately. Is it possible?
I'm using mandriva linux.
Thanks.

Hello,
we added 8 worksheets to the sagenb server.
The worksheets contain a course about ECC, and its done in a highly
interactive way.
See http://sagenb.org/home/pub/1126/ to http://sagenb.org/home/pub/1133.
We guess that a normal user wants to make use of a published worksheet

That the snapshots are no more saved in SWS files already saved a lot
of space.
But I hope you still can consider our request.

Hello everybody !
I'm using plot :
I can plot a curve by
sage: plot (sin(x), (x,-3,3))
or
sage: res = plot (sin(x), (x,-3,3)) ; res
I also can configure plot with optional parameters.
plot (sin(x), (x,-3,3), aspect_ratio=1)
And aspect_ratio is a method in res : I test it by res.[tab]
But I

FWIW, I implemented zsync and it isn't good. It's probably the same

Thanks for the tip Mike. I'll investigate this approach and report progress,
if I make some.
