Simple math problem. What does this equal?

Bro, as the whole physics folk, you have to use real notation, not bullshit ones. Explain me wtf is int(dx.f(x)) ?
big mood.. it's just notation and as such one ought to not get attached to it
Omg i love you bro... but accept it physicist destroys the math rules by using their notations...
notation has nothing to do with "rules"
It does in this problem. Sum Integral notation is universal int(f dx) if you interchange dx and f , f will be get out from integral like http://f.int (dx)
the higher you get in math you start to think of integration as an action on a function (linear operator).. Since we always talk about left-actions of operators it makes sense to think of the object ∫dx as "acting" on f(x)
This is exactly the reason why I *wouldn't* let you do it.. because I think of ∫ acting on differential forms, and it is weird to write the coefficiant of dx after it :P
you just think of iterated integration as successive action of a linear operator
Or a linear operator on differential forms (then the exp is just multiplied by the result)... Just one of these weird differences we gotta deal with :P
