I downloaded the latest 64-bit dmg of Sage for OS X and installed it.
It works, but I get a strange error message about sage-64.txt.
Specifically, if I put the following lines
in a sage file and run sage with that file for input, (here are the
lines)

Thanks. This version of sage worked fine for all the things I wanted
to do till today; I'll get the latest version immediately.
In case your questions were not merely rhetorical:
I did see that warning message, but since what I was doing was
graphical (i.e. numerical) and
it refers to symbolic co

You can also doing this using the built-in cube in the polyhedra
module. Polyhedra can be rescaled and translated; this does something
close to what it looked like you were trying:
sage: c = polytopes.n_cube(3)
sage: c2 = c*2
sage: p = point((2/3,2/3,0),color='green',size=10)
sage: c3 = (1/3)*c +

Hello Renato,
def s(x,n) :
return x/2 + add (cos(k*x) for k in [1..n])
n0 = 5;
plot(s(x,n0),(x,0,pi))
Thanks for clarification and tips :) Just a last doubt: if I
understand correctly, add() wants as argument an array like for
example [1,2,7,5], but running cos(k*x) for k in [1..n]

Hello,
I'd like to plot this function of x (latex code):
x/2 + sum_{r=1}^n cos(rx)
for some fixed n.
//A//
First, sum is designed for formal sum, not for truncate sum even if
sometimes it's possible.
But add is designed for these sums.
Second, expression doesn't evaluate the add(...) funct
Hi Renato!
I tried something a bit different
sage: reset()
sage: def s(x,n):^Jreturn x/2 + sum(cos(k*x),k,1,n)
:
sage: var('x,n,k')
(x, n, k)
sage: plot(s(x,5), (x,0,2*pi))
and it worked!
Enjoy!

Hello, I'd like to plot this function of x (latex code):
x/2 + sum_{r=1}^n cos(rx)
for some fixed n. However I'm running into problems... as I understand it
sage converts the sum of cosines in a sum of exponentials, but then somehow
doesn't get real values (and thus can't plot the function in the p

I updated mpi4py to 1.2.2 recently:

Do you think it's better to report it as a bug?

Thanks you very much for your reply
You're right, size affects the center too.
Not very intuituive but now, I know it.
I think this behaviour is quite surprising.
For example, with sphere, size doesn't affect center
