small question: integral e^(2x^2) dx

These types of 'e' integrals are difficult to integrate. As pka said, not by elementary means, i.e. parts, u-substitution, etc.
This can be done, but by other means, such as asymptotic series, error function, complex analysis, etc.
Anyway, I ran it through Maple and here's what she gave me:
\(\displaystyle \L\\\int{e^{4x^{2}}}dx=\frac{1}{4}\frac{\sqrt{\pi}erf(2\sqrt{-ln(e)})}{\sqrt{-ln(e)}}\)
I don't know why it displayed instead of
erf=error function
