Homework Help: An integration problem

  1. Feb 12, 2006 #1
    I'm doing a diff eq problem and I got stuck on the part where I have to integrate
    e^(x^2)dx. I tried using substitution but that didn't work :confused: ... any ideas?

    There's a good reason why you're getting stuck - there is no simple expression for the integral you're trying to evaluate.

    if it is definite integral you can evaluate by double integral and transformation to polar. if it is indefinite, a good way to evaluate it is integrate its polynomial expansion. but itself doesnt have an antiderivative

    Got it =) Thanks for pointing me in that direction.
