Or is there actually a value for I?

amtran_bus · Answer

I mean, how can you get an actual number with infinity on top?

irishboy123 · Answer

you're integrating f(v) dx.

so v is assumed a constant so you get what MW throws at you.  makes sense

amtran_bus · Answer

But there is not an x there. Check the screenshot

irishboy123 · Answer

there is , and in the MW output

amtran_bus · Answer

So that means it is divergent then, right?

I say by what I got from the last problem this one is.

dan815 · Answer

yes

dan815 · Answer

think of all divergent series, represent them in continuos form,

amtran_bus · Answer

Thanks so much dan.

dan815 · Answer

mhm sure :)

irishboy123 · Answer

that is a straight integral: $-\frac{5}{14}e^{-7x^2}$ from $ - \infty \ to + \infty$

at $ - \infty $ to have a problem

amtran_bus · Answer

Ok, that makes some sense. How do I go about these?

amtran_bus · Answer

The one marked was by mistake.

amtran_bus · Answer

Again, I know the same way you are helping me with, but the dx is in a weird place.
