Hi Paul,
This is a bug. I assume that the result is mathematically correct but
it is not a good transformation of the expression.
Can you open a GitHub issue for this and link back to this mailing
list thread (and send the link to the issue back here as well)?
The problem is with Pow.conjugate
from sympy import Expr, log, Abs, sqrt
from sympy.abc import x, u
class CustomExpr(Expr):
pass
expr = log(Abs(sqrt(1+2/x)-1))
print(expr.subs(x, u))
print(expr.subs(x, CustomExpr(u)))
The first one prints, as expected, log(|sqrt(1 + 2/u) - 1|)
But the second prints something different:
log(sqr
