Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to solve the definite integral between 0 and inf of:

exp(a*x^2 + b*x + c)

--------------------- dx

1 + exp(m*x + n)

with a,b,c,m,n real numbers and a < 0 (negative number so it converges).

I've read in the forum's rules that I have to post the work that I have done to get an answer but I have nothing reasonable to post (I have tried many alternatives but I didn't suceed, sorry)

A way to obtain the exact solution would be perfect but an approximate result, even an upper/lowerbound would be fine as well.

Any idea or help, please?

Thanks in advance,

FC.
