QUESTION
I tried to calculate the numeric values of the result of the solve
function. In WolframAlpha it is called "Approximate forms".
This are my equations:
...ANSWER

QUESTION
I came across a problem substituting variables in logical formulas in Sympy. Here's a minimal example -
...ANSWER
Answered 2018-Jun-25 at 02:34This is a bug in SymPy. Class Not
does not have is_commutative
property set, and does not inherit it either. As a result, Nand(x, y)
(which is Not(And(x, y))
has "None" for "commutative" assumption, and this is not acceptable for Dummy creation method, which attempts to create a dummy symbol with the same assumptions. This problem does not occur for And
, because And
inherits is_commutative=True
from LatticeOp
class.
The way to fix this in SymPy seems to be to add is_commutative=True
to class Not
.
Workarounds on user side include: using Or(Not(x), Not(y))
instead of Nand(x, y)
