Re: Condition , FullSimplify

>> I find it useful and practical using the first notation.

I don't see how, since it doesn't work! (You wouldn't be asking the question, if it did.)

The problem is that expr/;condition//FullSimplify doesn't mean FullSimplify[expr,cond] in Mathematica; it's really just that simple.

It does mean FullSimplify[expr/;condition], but that's not likely to be of much use. As far as I can tell, expr/;condition is useless without SetDelayed or RuleDelayed.
