The integral of e^(x^2) cannot be expressed in terms of elementary functions. Instead, it relates to the special error function, erf(z), defined by a specific integral. The discussion also raises the possibility of evaluating definite integrals involving e^(x^2) using special techniques. Additionally, a minor note on the correct spelling of "integration" was mentioned. Overall, the integration of e^(x^2) is a complex topic that requires advanced mathematical concepts.
