Re: Real Solutions


Hi,

in

Solve[x == y, y]

with

{{y -> x}}

is it a real solution ? or not ?
It depend on x right ? and for a symbolic
solution it is impossible to give you the
real only solutions if you don't
provide more information.
And Assuming[], Simplify[], FullSimplify[] and
Refine[] should help.

Regards
   Jens
