Just try :
-
Z_T, t = ZZ['x'].objgen()
print factor(6*t+3)
print factor(6*x+3)

You will se that you need to use the right ring of polynomials.

Hello.
Is it possible to ask to sage to give formulas for simple recursive
sequences ?
For example, *w_{n+1} = (n+1)/n*w_n + 1/n* with *w_0 = 1* , we have *w_n
= 2 n + 1* . More simple example could be arithmetico-geometrical sequences
*w_{n+1} = a*w_n + b* .

I do not think that is really a convention, but it is very logical because
1.1 can also be a float result given by Python. But floats and decimals are

Instead of *not(S == [])*, Python allows to simply use *not S*, and instead
of *not(r == 0)* you can use *r != 0*, and lastly instead of *S = S + [r]* you
can use *S.append(r)*, or *S += [r]* if you do not want to use OOP.

Hello.
This is certainly due to the way Python manages unhashable variables. If
you type p6 is c6, you will obtain True, in other words, p6 and c6 are two
references to the same object.
Using p6=c6.copy() will do the job.

Thanks for the reactivity. I have no time today to implement this but
indeed it is a very simple task to do. If no one gives you something, I can
try to adapt your code. Just tell us in this discussion if someone has done

Indeed, I'm french with a more or less knowledge of english... ;-) I was
just thinking of stacking one curve upon another.

Hello,
here is a way to draw several functions on the same graphic.

I think also that there is a problem.
More simply, something like

var('a')
plot(bool(a^2==3),a,1,7)

this is certainly a bug. The error comes from (a/s**2).is_polynomial(s).

I can understand an automatic printing fro the very last string even if it
is not preceded by a print function, but I do not see a reason to print all

Hello,
when I download a Sage sheet containing one plot, I do not have the picture
output corresponding to the plot.
Indeed, I will type one Python code so as to build a LaTeX from my Sage

locally. No so hard to do but it will
Great fro the future.
