Integral

Find

Integrate (e^(x^2))dx

There was a question a while ago on the Dr. Math Forum, it might be usefull:

http://mathforum.org/dr.math/problems/jaw6.1.96.html

You can find some info on the erf-function here:

http://mathforum.org/dr.math/problem...ez3.26.98.html

your talking about a popular integral from statistics. You need to switch coordinate systems to evaluate it. Think college calculus level 3

I just fed the integral into the 'Integrator' at http://integrals.wolfram.com/

It spat the following out... http://integrals.wolfram.com/graphic...%28x%5E2%29%29

Information on the Erfi function can be found here... http://mathworld.wolfram.com/Erfi.html

Hope this helps.

the integral of e^f(x) is f'(x)e^f(x), therefore e^(x^2) = 2xe^(x^2).

make any sense?

e^function = derivated of function x e^function

dude, what you have done is called differentiation.

for example:

Differentiation [e^(ax)] = a.e^(ax) .dx

Integral [e^(ax) .dx] = [(e^(ax))/a] + c
