I have a short pull request for review: https://github.com/sympy/sympy/pull/596
as_independent uses has to determine whether an expression has the symbol of interest or not. A potential problem is that an expression may have a bound symbol x that is not part of the free symbols of the expression. Now only subexpressions that don't have the symbol in the free symbols will be returned as independent. Could someone take a look, please? -- You received this message because you are subscribed to the Google Groups "sympy" group. To post to this group, send email to sympy@googlegroups.com.
