I banned him. He did mention R and octave in his link
but not Sage. Legit surveys usually give a lengthy
explanation about how the info will be used etc. This one did not.

Is there an need for more open source math tools in
for-profit companies? If so, would targeted training and support help meet
this need while benefiting the open source community? Please share your

Correct, because concerning to the perecedence list on
http://www.sagemath.org/doc/tutorial/appendix.html + has a higher
precedence than ==. The text says, that the table is based on the table
in § 5.14 of the /Python Language Reference Manual/, but that
Thank you very much for your kind help.

Probably there is a better way of doing it, but the following works:
Transform the problem into a matrix: One row for each polynomial, one
column for each monomial that occurs in one of the polynomials, and
th
Sorry again. Dependency needs over integer.

'Linear over ZZ' or 'linear over R'?
If it is the latter, the following might help (but is only implemented
if you have polynomials over a field, not over ZZ):

Hi,
No, my polynomials are not homogeneous and are of different degree. Suppose:
R.=ZZ[]
f1=1+x1+x2+x1*x2
f2=1+x1+x3+x1*x3
I want to find linear dependence of the set polynomials {f1,f2,f1*f2,
x1*f2,x2*f2}
With regards,
Santanu

When you talk about linear indepence of polynomials, you probably
assume that they are all homogeneou
Hi,
Suppose f1, f2,,f10 are polynomials over 20 variables over integers.
How one can check weather they are linearly independent or not in Sage?
