thanks Marshall,
I tried viewer option but this is not working for me (firefox,ubuntu)
even if it is already better than a yellow warning.
I used example from video3 of http://www.sagemath.org/help-video.html
def f(x,y): return sin(x-y)*y*cos(x)
plot3d(f(x,y),(x-3,3),(y,-3,3))
but all I see is a
Hi,
I'm trying to install sage4.6 on a modest eeepc and I've decided to
not install any Java prog for memory reasons. All is perfect since
mostly everything is included, except plot3d.
Do you know any non-java project I can benefit from to get the basic
functionalities of plot3d (display, shadows,

'Eval' can do that :
def ashow(v):
show("$"+v+"=%s$"%latex(eval(v)))
b=2/3
ashow('b')
Hope that helps

In the other hand, is there any difference between $$ ... $$ and ... ?

SAGE doesn't know anymore that exp() is strictly ascending.
(assume(b<0) doesn't work anymore)
