I think you mean that the deadline is December 12th, 2008

Since I see no difference at all with the same
Hi,
x = polygen() returns an object of type
Polynomial_generic_dense, while .inject_variables() injects x of
type Polynomial_rational_dense.
Why the difference?
This was a problem for a student today, who was using polygen(), whose
returnee will not simplify x^3/x^2, whereas inject_variables()

Hello,
I would like to pick out individual eigenvectors of a matrix, and then
be able to manipulate them as vectors. I tried the following:

| Sage Version 3.2, Release Date: 2008-11-20 |
| Type noteboo
I get
sage: var('x')
x
sage: f = sin(x)/x
sage: g = f.integrate(x)
sage: g
integrate(sin(x)/x, x)
in 3.2.1.rc1. Personally, I would call this a missing feature, not a bug.
Interestingly, it can compute
sage: f.integrate(x,0,infinity)
pi/2
sage: f.integrate(x,-infinity,infinity)
pi
