In summary, the conversation discusses solving a problem involving the integral of an exponential function with a power of -x^2. The person is having trouble solving it for arbitrary limits, and someone suggests looking at the gaussian function and the error function. The person acknowledges that the error function is non-elementary, meaning it cannot be solved in terms of elementary functions.

i am solving a problem that involves taking the integral of an exponential to the power of -x^2. I would have no problem solving this integral if the limits were 0 to infinity but the limits i am solving for are an arbitrary a to infinity. Can anybody help?

Sounds like a gaussian function:

The anti-derivative is the error function, which is nonelementary.

that verifies what i was thinking but i am still having trouble going about solving it. I think I am just not sure where to start. Thanks though at least I know I am not completely off track

You can't solve it, in terms of elementary functions, that is. As Tac-Tics already said, the error function is non-elementary.
