Sage use
This is very very small RAM for 7 sage notebooks

I have an Ubuntu 9.04 Xen virtual machine with 350 Mb RAM.
(from linode.com hosting services)
I tried to have 7 people run notebooks off this server simultaneously
and it was painfully slow for each.
I started the server with this command...

See the first question here:

I have the same problem. I have been using Sage 3.2.3 on my Win XP SP2
with no problem, but I tried installing 4.1.1 version and it does
exactly the same as what you see. Any help is appreciated..please

This \over is from Maxima.
try
a1=maxima.solve(x^2-x-3,x)
R1=a1[0]
R3=maxima.rhs(R1).sage()
latex(R3)

Hey, thanks a lot. I was able to do it, though for my project the R^2
value constantly came out to .

Yes, your right. I am latexing a value from maxima.solve(x^2-x-3,x).
Then maxima.rhs(). Then latexing the value. It still gives me the
\over. I am using 3.4.
When I assign it to a variable it works as below. If you would try
a1=maxima.solve(x^2-x-3,x)
R1=a1[0]
R3=maxima.rhs[R1]
latex(R3)
prod

I would probably first look at using scipy.stats. For example, a linear
regression line can be found like this (from
http://www2.warwick.ac.uk/fac/sci/moac/currentstuden
Hm, this is my Sage 4.1.1
a1=-(sqrt(13)-1)/2
latex(a1)
output is -\frac{1}{2} \, \sqrt{13} + \frac{1}{2}
You may have old version of Sage
latex(-{{\sqrt[13]-1\over[2}}) produces error

If I have this a1=-(sqrt(13)-1)/2 in a variable, then latex(a1) it
produces -{{\sqrt[13]-1\over[2}}.
If I do latex(-{{\sqrt[13]-1\over[2}}) get \frac{1-\sqrt{13}}{2},
which is what I want.
This is in a function. I need the latter. The \over does not do the
pretty print.
Is there a work around
Is there any way to calculate regression lines and regression (R^2)
for a set of points in sage?

Thanks; your answer explained it. I don't understand why Python works
that way, but I'll bet there's a good reason.

Let me follow up: I don't get this either, and it may get to the heart
of the distinction more easily.
sage: f(yvar = 2)
x^2 + y^2
sage: f(y = 2)
x^2 + 4

Doing f
Hi,
Consider the following expression sequence:
sage: var('y')
y
sage: f = x**2 + y**2
sage: yvar = y
sage: xvar = x
sage: f(yvar = xvar)
x^2 + y^2
sage: f({yvar:xvar})
2*x^2
I was under the impression that both forms of substitution should
return the same thing, but apparently not. Can someone

Thank you for your help. I posted the patch
