Even with `force=True` I don't like the symbolic (do-nothing?) factoring that results.

The following is also not solved completely: ```python >>> eqs (A*(S + 1) + I*S, A*(S + 3) + I*(S + 1)) >>> sols = [{A:0,I:0}, {A:-I/2,S:1}] >>> [eqs.xreplace(s) for...

There are 8 different exponential function in your equations: replace them with symbols and keep numerators ```python >>> eqs = Tuple(*liste) >>> reps = dict(list(zip(eqs.atoms(exp), numbered_symbols('e')))) >>> eq1 = [i.as_numer_denom()[0]...

You can reduce the complexity of the problem considerably by using a change of variables and solving for those new variables instead: basically we will let 1/(1 + exp(-x)) =...

This is a known issue: `QOSINE` are the clashing single letters (as documented in abc.py).

> closed as intended behavior But it's a pretty big gotcha. I wonder why E instead of e (or I instead of i) was chosen as the representation. But either...

Great points added by both of you. Thanks for entertaining the idea of a better way. Note, too, that `abc` provides some guidance: >The module also defines some special names...

Just a few questions and suggestions added here.
