How did you install?
Source, binary, or ppa?

Hello,
if you want to work with long table-array, it could be useful to use numpy.

I have similar issues when running your code. However, the same code works
if you do not do implicit plotting:
var('x y')
xrange = (x,0,5)
yrange = (y,0,5)
f1 = plot(x**2,xrange,color='red',legend_label='x^2 - 4x + y^2 == 0')
f2 = plot(x,xrange,legend_label='x*y==1')
result = f1+f2
result.legend
Hi, I try to add legend on a plot (created below) but doesn't seem to have
any success. There was no error, the legends just won't show up.
var('x y')
xrange = (x,0,5)
yrange = (y,0,5)
f1 =
implicit_plot(x**2-4*x+y**2==0,xrange,yrange,color='red',linewidth=5,legend_label='x^2
- 4x + y^2 == 0
I was wondering if there is a process for importing libraries that do not seem

to do the following import:

Dear all,
I kindly ask for your feedback on the following.
My work involves the use of big lists that are of two kinds:
a) lists of integers
b) lists of lists of integers
The contents of those lists come from quite long computations and I need to
reuse those tuples often,
so it is necessary t

Hi Peter,
Thanks for your suggestion, it's something I hadn't considered specifying
for all of my variables. I managed to avoid the '_first_ngens' by
restructuring the code, and your comment about making sure that everything
is actually an integer saved me a lot of time fixing the next error.

Hi Dima,

Return the (left) nullity of this matrix, which is the dimension of

It is not a bug, but a consequence of a different convention. In Sage,
nullity means left nullity, i.e. the dimension of the left kernel. In this
example, m.nullity() + m.rank() = m.nrows(). For the more common right
nullity (resp. kernel), use m.right_nullity() (resp. m.right_kernel())
