sorry for the late answer.
After some investigations on the internet, I did not find any convenient
solution.
My concern being on polynomials, I ended up doing some copy/paste of my
expressions and working in another window with a polynomial ring defined
the following way :
R. = QQ[]
R. = Polyn
I had the same problem and deleting the 'sage_notebook.sagenb' directory
from '~/.sage/' resolved it.
Thanks for the tip.

Thank you for your answer and sorry for the typo mistake.
Your solution works well with the example given but doesn't work as I would
like with exponents (x^2, ...).
What I would like to get is Sage returning expressions with coefficients
sorted by the value of the exponents, like when using mul
Hello,
I would like to factorize an expression with sage that contains constant
variables (i.e. parameters), but I cannot figure out how to do that.
Here is an example : x, y are variables and A is a parameter
*
var('A x y')
f = A*x + x + A^2*exp(y) + y
print (f.factor())

Hello,
I used sage to find the root (named P2plus) of an equation. The variable is
P1plus and there are 3 parameters, M1, M2 and gamma. The expression of the
root (P2plus) being complicated, and as I am interested in its behavior for
small values of P1plus, I asked Sage for the Taylor expansion
I encounter a problem splitting and equation on several lines using the
backslash. Splitting works for any line, except for symbolic expressions
where the error message '
SyntaxError: invalid syntax' occurs.
A little example.
* the following lines work :
f = x^2 \
+ 1
print f
* but those d
As Sage fails to solve the non-linear (2nd order polynomial) systems am I
interested in, I tried to force the substitution of variables in the system
to obtain an answer.
In the example given below, the system corresponds to :
g1 = 0
g2 = 0
where the unknowns are P1m and P2p. The others variable

Hello,
I am new to Sage and I want to use it to solve non-linear systems, used to
model physical phenomenons. I unfortunately met some problems trying to solve a
non-linear system composed of 3 polynoms (2nd order)
I first successfully solved the linear problem, but when I try with the
non-line
