1. The problem statement, all variables and given/known data

I'm need to integrate the function


which using wolfram alpha gives a function of the 'hypergeometric function' [tex]_2F_1(a,b;c;z)[/tex]


I'm writing a program to calculate the integral at diffent values of x. The problem is that for most of my data, x gives values of [tex]\left|B^2x^2\right|> 1[/tex] and it seems that calculating it at those points becomes much more complicated, beyond my mathematical capabilities.

3. The attempt at a solution

messing about with wolfram it seems that as long as z<0 the solution is a real number, so it should be possible to calculate it in my program. However the GNU scientific library is only capable of calculating it for |z|<1.
