One can discuss if in limits of f(x,n) as n-->oo
x may depend on n or not but in the following version:
sage: assume(x>-0.99,x<0.99)
sage: n=var('n')
sage: sage: limit(x^(n+1)/(1-x), n=infinity)
-limit(x^(n + 1), n, +Infinity)/(x - 1)
sage: assume(x>0)
sage: sage: limit(x^(n+1)/(1-x), n=infinit

given an expression f of the form c1*t1 + c2*t2 + .. +cn*tn, I want to
extract from f the list of 'terms' [t1..tn] .. is there some Sage function
that can help do this ? Thanks ,
For example
3/5*x*y + 5*y + 3*z > [x*y,y,z]
3*x^2 -> [x^2]
x*y -> [x*y]

I'm confused. I was going to recommend numpy.seterr(all='ignore')
before I read this, maybe wrapping plot to restore the original state
after the call.. but now I'm not sure what kind of solution you
(Respectfully) Then why does splitting the range of values for x into
positive, zero and negative ranges work?

Hi, there's an error in
http://www.sagemath.org/doc/numerical_sage/numpy.html
at the part where says
"You can see that numpy.meshgrid() produces a pair of matrices, here
denoted xx and yy, such that (xx[i,j],yy[i,j]) has coordinates
(x[i],y[j])."
(It's just after the meshgrid() example). (xx[i,
I want to get rid of them. I am pretty sure I'm not dividing by zero
anywhere; 1/sqrt(f**2+1) really shouldn't ever be zero here. Any
ideas?
y = var('y')
g = 1
P=plot_slope_field(g,(x,3,4),(y,-1,1))

And when I say "get rid of", I mean by tomorrow morning in a talk I'm
giving. This is almost
In this case, you can reinstall the sagenb spkg, I think. Let us know
if that works. The Jmol upgrade is still experimental, though
definitely wending its way toward completion...

How can installed optional spkgs be removed from the current sage
installation. I have installed an jmol upgrade package which has
failed to work and now I'd like to revert to whatever the previous
version was. Is this possible?

Hi
I don't know why the function "A=H.point()" at the following program
for the finite field with size 101^5 does not work with this error as
below.
But for the finite field with size 101^2 there is no problem.
By the way, I use this PC:

On Monday or Wed., I think I'd like to show my intro number theory
course a cool new result we would have no hope of actually examining,
but whose result they can understand - the Barnet-Lamb/Geraghty/Harris/
Taylor result on number of ways to write a prime as a sum of twelve
squares, which relies

Without additional assumption that x is constant
the limit is not zero (take for example x=(1/2)^(1/(n+1))
(W... alpha:
Assuming[x=const,x<1,x>0];Limit[x^(n+1)/(1-x),n->+Infinity] 0 OK,
Assuming[x<1,x>0];Limit[x^(n+1)/(1-x),n->+Infinity] unevaluated OK)
