or the following url Functions without Antiderivatives by TR Smith with the follwing extract:

Here is a list of basic exponential forms that have no antiderivatives
• e^(x^2) and e^(-x^2)
• e^(x^3) and e^(-x^3)

Yes, the function has no closed form antiderivative. But that does not matter here because the 15C is calculating a definite integral by numeric integration. Exactly because there is no analytic solution. ;-)

For the math geeks: somehow I feel that in this case some variable substitution should be applied to calculate the integral easier and faster. Maybe someone has an idea here?
