Hello,
I have been usage Sage for a few months. Up to now, plotting,
polynomials, and arithmetic functions have been running fine.
Now I'm trying to use the symbolic calculation skills of Sage, but ...
I am getting the error : "unable to simplify to float approximation"
when running, for
Hi all
I am a physicist and a new user of Sage. I used the following command on Sage
Version 5.1, Release Date: 2012-07-09, to get the expression of eigenvalue and
eigenvectors of the symmetric real 3x3 matrix.
var('g11,g12,g13,g22,g23,g33',domain='real')
Hello
I make computation with complex numbers and symbolic expression. My
problem is on the multiplication between complex number, symbolic
expression and a negative number. I give an example :
sage: P=(1+i)*x
sage: Q=-P
sage: Q
-(I - 1)*x
sage: P+Q
0
On the line 4 it should be -(i+1)*x instead

Hello,
I'm trying to parse symbolic expressions, but got stuck very quickly.
If I say:
(x^2).operator()
I get:
built-in function pow
If I say:
pow
I also get:
built-in function pow
But if I say:
(x^2).operator()==pow
I get:
False
How do I properly test if the topmost operation of an
