gamma function

For the integral of e^(x^4). Wolfram says the answer is the incomplete gamma function, (-(x ?(1/4, -x^4))/(4 (-x^4)^(1/4)))
What is the incomplete gamma mean?

The question involved is finding volume by revolving the solid bounded by, y=e^(-x^2), y=0, x=-1, x=1. Round the x axis.

thanks

Re: gamma function

If you're squaring the function then you shouldn't get but
