New issue 2009 by torstenmarcoknodt: solve((x-y,y),x) is None
http://code.google.com/p/sympy/issues/detail?id=2009
Hello,
I have started working with sympy (0.6.7) and found that:
sympy.solve((sympy.abc.x-sympy.abc.y,sympy.abc.y),sympy.abc.x)
evaluates to None
Obviously the result should be [0].
Moreover
sympy.solve((sympy.abc.x-sympy.abc.y,sympy.abc.y),sympy.abc.y)
also evaluates to None.
The following works:
sympy.solve((sympy.abc.x),sympy.abc.x)
evaluates to [0].
For the case this is not supported so far, it should at least raise an
exception.
Regards
Torsten Knodt
