I was able to rebase and get that code wor
b.com/sympy/sympy/issues/18348. There is a PR
refactoring the code for exact ODEs which seems abandoned at
https://github.com/sympy/sympy/pull/18887. Would it be okay if I tried to
finish it?

Hi, out of curiosity I wanted to know why does this:
from sympy.solvers import solve
from sympy import Symbol,exp
x=Symbol("x")
solve(x*10e-4+exp(x),x)
runs much faster than this:
from sympy.solvers import solve
from sympy import Symbol,exp
x=Symbol("x")
solve(x+exp(x/10e-4),x)
(?) Thanks!

Hi Aaron,
Can you explain the thinking behind the Symbol class? I looked at the
doc string but it's not clear how general this kind of object is.
Thanks

Hi Aaron,
The Set class is important to have as a master class for all kinds of
other classes which should exist, such as Group, Field, Vector space,
Algebra, etc. As it is in Category theory.
A Python set may indeed be a good place to start, but as you suggest,
it would only be a finite set of
what we do every day in what I would consider is the
most mainstream mathematics.
Let me know what you think.
Marco

Thank you for this - I am studying it and it definitely has some of
the flavour of what i'm thinking of. Once I understand it better I
can say more.

I was very impressed by the description of SymPy here:
http://www.euroscipy.org/presentations/slides/index.html
and especially slide 14 "Internals: Object oriented model".
I have a couple of general questions about how Object-oriented SymPy
is. I'm a mathematician and would like to use or exten
