Could you do `print filldedent(R);print filldedent(L)` so I can see what
the expressions are that you are trying to solve?
Sorry my list L of 4 relationals was latter renamed R... Here they are

Oups I just saw that my first and second relationals are the same. So I
have to solve for only 3 relationals.
I just went to try the wolfram alpha online calculator, I got :
1/ for the first relational :

Suppose that I have an expression
e = x**2+sqrt(a**2*b**2)
What is the best way to assign to expression assumption that all variables
are Positive, so that equivalent of e is x**2+ab?

It should be done like this:

I'm having some problems getting sympy to compute eigenvalues of a
matrix with symbolic coefficients.
A trivial example is:
In [4]: M = Matrix([[y, 0], [0, z]])
In [5]: M
Out[5]:
⎡y 0⎤
⎢⎥
⎣0 z⎦
In [6]: M.eigenvals()
Out[6]:
⎧ ____ ⎫

I know this way, but is there any way to change this after symbol creation?

Hi there,
Using sympy0.7.6.win32, I run the following python script to try to find
the intersection of a Line3D and a Plane. The coordinates for
Point3D are from my intermediate result. I test the script in python 2.7.8
(Case 1) and python 3.4.2 (Case 2) and got different results.
