sin(x).series(x == 3, 5) to get a taylor expansion about x = 3. I did this only for consistency with GiNaC, since that is what GiNaC does. > > sympy uses > > sin(x).series(x, 0, 5) > > and sage uses > > sin(x).taylor(x, 0, 5) Using taylor is really dumb. It is inconsistent with every other system and is confusion since it can give Laurent series. > > and this is unfortunate. I would like to use just one interface. Yep. That's precisely what we'll have to have in order to have a sympy + pynac system.
