Hi, I'm glad to help.
An issue has been created on this bug and I've uploaded a proposed patch file. http://code.google.com/p/sympy/issues/detail?id=1342&sort=-id Running the tests seems to work, I'm not sure what the 'xfailed' tests signify however: ===== tests finished: 1347 passed, 32 xfailed, 1 xpassed in 100.83 seconds ===== Also a simple test for the bug passes: from sympy import * x,a,b = symbols('x,a,b') f1 = 1/(1+a*x) f2 = 1/(1+(a+b)*x) assert simplify(f1.series(x,0,6).subs(a,a+b) - f2.series(x,0,6)) == O (x**6) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
