Question

is it possible to have double improper integrals? just yes or no....coz i'd like to see how to do them if yes >:))

anonymous · Answer

yes

unklerhaukus · Answer

$$\iint \text d x^2=\int x+c~~\text dx=\frac{x^2}2+cx+d$$

lgbasallote · Answer

lol that's INDEFINITE integral :P $$\int_a^\infty F(x) dx$$ that's the improper integral haha

anonymous · Answer

is i m right lgba...?

lgbasallote · Answer

double improper let's say $$\int_0^\infty \int_\infty^0 xy dxdy$$

lgbasallote · Answer

does that happen?

unklerhaukus · Answer

ah yes @lgbasallote i got my language mixed up

lgbasallote · Answer

so does it happen?

unklerhaukus · Answer

would this count
$$\int\limits_{-\infty}^{\infty}\text d x$$

unklerhaukus · Answer

it is doubley improper

lgbasallote · Answer

lol :P

lgbasallote · Answer

the one i posted....does it happen?

unklerhaukus · Answer

i would be surprised if it did not happen, but you limits are upside down on the inner integral

lgbasallote · Answer

improper integrals =_=

lgbasallote · Answer

how could it be upside down @UnkleRhaukus i made the problem :P you cant tell the asker what he wants to ask >:)))

unklerhaukus · Answer

the lowest number on the bottom limit makes more sense as you are integrating from left to right

lgbasallote · Answer

so bottomline..it's possible?

anonymous · Answer

Yeah, sure. You could certainly have one. We use improper integrals often when we have asymptotic curves like this:
|dw:1336831376041:dw|
