Hello,
the following code prints
*21**(x^2 + 2*x)/(28*x^2 - 3*x - 40)
but I would simply like to have
(21*x^2 + 42*x)/(28*x^2 - 3*x - 40)
Can I acheive this ?
Best regards.
C.
=== CODE ===
param = []
for i in range(8):
param.append(randint(-10,10))
num(x) = (param[0]*x -
Helloo everybody !
This is what I spent the last hour finding :
sage: x = 1/2
sage: x
1/2
sage: x//2
1/4
I got some variable x as input, which was of rational type when I
expected it to be integer type (does not matter, this rational was
equal to an integer in my case). Unfortunately, x//2

Does sage have any functions for div/grad/curl/del squared?
Thanks,

If you really want, you can access PARI's ellsearch through Sage using
something like
pari('''ellsearch(11a1)''')
But, as others have said, Sage itself also contains the elliptic curve
database, so why bother?

The cartesian product of two polyhedra doesn't work if their dimensions are
different:
Consider the following (just run on sagenb.org):
sage: B1 = Polyhedron(vertice=[(0,),(1,)])
sage: B1
A 1-dimensional polyhedron in ZZ^1 defined as the convex hull of 2
vertices
sage: B2 = B1*B1
sage: B1
Thanks, this is now http://trac.sagemath.org/ticket/15253
