Math question

[Guest]

What does it mean that e^x² can't be integrated? How would one find the area under the curve then, only by approximate integration (ex: Simpson's rule, etc)?

fuck u...

what does the shape of the cuve look like?

can u post an image or something?

if u ask it to plot e^(x^2) you'll see your answer I think.

Seems like the area is infinite.

same with e^x^2 (different from above, but still infinite)

actually - i just realized my comments make no sense - integration is within bounds, else any graph would be infinite

:icon27:

It can be integrated, it just doesn't have a clean, closed-form solution. You have to use mathematical jiggery-pokery to integrate it. I don't recall the technique for e^x^2, but I know that for e^(-(x^2+y^2)) you can switch to polar coordinates and fairly easily inegrate it by substitution. There's another trick you have to pull to complete it, but it escapes me at the moment.

You know what? I don't miss those two-page problems one bit!

The pisser is that I was pretty good at intermediate calc too. Problem is, when you never use a learned technique - and you know you never will - you piss it right out your brain hours after the last test...

I have a math question too

If a guy named "Henk" has four apples, then how much apples would another guy, going by the name of "Klaus" have?

[corsair]

Is that above your level?

No, just don't care that much. 5.

God I hate math.
