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

  • IrishBoy123
you're integrating f(v) dx. so v is assumed a constant so you get what MW throws at you. makes sense

  • AmTran_Bus
But there is not an x there. Check the screenshot
IrishBoy123
  • IrishBoy123
there is , and in the MW output

So that means it is divergent then, right?

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

yes

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

mhm sure :)

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

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

The one marked was by mistake.

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