What is the integral of e^(x^2)

Question

anonymous · Answer

It's the error function (also called the Gauss error function) It is defined as: erf(x) = (2/√π)∫ (from 0 to x) e^(-t^2) dt ----> ∫ (from 0 to x) e^(-t^2) dt =[ (√π)erf(x)]/2 http://mathworld.wolfram.com/Erf.html

Is this a localised or indefinite integral?

anonymous · Answer

I guess the problem is that we don't have a definition for integration

This should be able to help.

anonymous · Answer

Isn't the erf just for things like e^-x^2 and not e^x^2?

anonymous · Answer

Yeah apparently so,I still have to understand what it really is

anonymous · Answer

Well, just above the erf on the wiki site, I think there's your answer.
