yes
OpenStudy (unklerhaukus):
\[\iint \text d x^2=\int x+c~~\text dx=\frac{x^2}2+cx+d\]
OpenStudy (lgbasallote):
lol that's INDEFINITE integral :P \[\int_a^\infty F(x) dx\] that's the improper integral haha
OpenStudy (anonymous):
is i m right lgba...?
OpenStudy (lgbasallote):
double improper let's say \[\int_0^\infty \int_\infty^0 xy dxdy\]

does that happen?
OpenStudy (unklerhaukus):
ah yes @lgbasallote i got my language mixed up
OpenStudy (lgbasallote):
so does it happen?
OpenStudy (unklerhaukus):
would this count
\[\int\limits_{-\infty}^{\infty}\text d x\]
OpenStudy (unklerhaukus):
it is doubley improper

lol :P
OpenStudy (lgbasallote):
the one i posted....does it happen?
OpenStudy (unklerhaukus):
i would be surprised if it did not happen, but you limits are upside down on the inner integral
OpenStudy (lgbasallote):
improper integrals =_=
OpenStudy (lgbasallote):
how could it be upside down @UnkleRhaukus i made the problem :P you cant tell the asker what he wants to ask >:)))

the lowest number on the bottom limit makes more sense as you are integrating from left to right
OpenStudy (lgbasallote):
so bottomline..it's possible?
OpenStudy (anonymous):
Yeah, sure. You could certainly have one. We use improper integrals often when we have asymptotic curves like this:
|dw:1336831376041:dw|
