Comment (by zimmerma):
Michael,
ok, we will modify our book, taking into account that by default symbolic
variables are considered complex.
However I'm not happy with this ticket (#12780). Before we had (say in
5.1):
{{{
sage: assume(x,'real')
sage: sqrt(x^2).simplify_radical()
abs(x)
}}}
This was correct. And now (say in 5.8):
{{{
sage: assume(x,'real')
sage: sqrt(x^2).simplify_radical()
x
}}}
This is wrong, thus we have a regression with this ticket.
Paul
Note: I didn't call {{{radcan}}}, but {{{simplify_radical}}}...
