Re: Re: Help for an integral

Most integrals of e^-x^2 should resolve out to a function of the cumulative
standard normal distribution. This has many simple 5-7 term algebraic
approximations, although you are right there is not close form or analytic
solution. Is there a way to force Mathematica to use this in a solution? I
ask because I want to develop the standard models using Mathematica and then
branch out into non-standard models.

Not even simple e^-x^2 can be integrated exactly between finite
intervals. You could try writing a function of a that will return a
numerical value of the integral (just use NIntegrate).
