Upon reflection, it looks like the first item of the quadruple is the
normal. True?

Apologies if this is a FAQ or is somewhere in the docs; I could only

What is the format of the Graphics3d Object's face_list()? Here's
sample output:
[(2.0, 0.0, -1.5011), (1.9917900138232461, 0.0
Thanks, Nils. That's actually very helpful to know.

If you use "solution_dict=true", you get the solutions back in a form
that is probably more suita
Hi all,
I've just upgraded form Unbuntu 9.10, on which I tried compiling from
source to Ubuntu10.04 on which I installed the pre-fab binary. So, on
10.04 it seemed to be working but I've had a problem with the notebook
disappearing and this is the second time it's happened now.
$sage -n
Please wa
Thanks, Phil. That worked like a dream! Much obliged.

Hi,

Try this:
sage: N=100
sage: D=5
sage: [i for i in primes(3,N+1) if not i.divides(D)]
[3, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71,

Like this:
sage: sol = solve([x+y==6, x-y==4], x, y)
sage: sol[0]
[x == 5, y == 1]
sage: sol[0][0]
x == 5
sage: sol[0][0].r
Q1. How can I extract elements from a solution set?
For example, consider:
sage: x, y = var('x, y')
sage: solve([x+y==6, x-y==4], x, y)
[[x == 5, y == 1]]
How can I extract these values for x and y so that I can, for
instance, use them as the coefficients for a polynomial f(t)=x+ty so
that I hav

Hi Michael
have you tried just typing
sage
after the system prompt (something ending with $)

In the past, there was a Debian binary among the provided binaries,
and this served as a fallback in the event that other binaries failed
for a particular Linux distribution.
I just downloaded all existing binaries -- all of them -- and tried to
install them in Fedora 13. None of them successfully
Hello!
Since yesterday I have been trying to Install Sage 4.5.2 on my
netbook. After many years of using Windows I just changed to Linux (32
Bit, Opensuse 11), so I'm not yet used to working with this operating
