Success! By using Gauss–Kronrod quadrature I was able to successfully numerically integrate this function. Thanks for you help! big_smile

Both A and B are constants which are between 0 and 1. The top bracket is just a bracket. wink

I'm currently having difficulties trying to numerically integrate the following

where A and B are constants. I need to determine this integral for values all values x such that

. I have solved this integral analytically for the special case of
successfully. I am now interested in examining the integral for cases when alpha does not equal one. However, I am currently unable to numerically integrate this function.  I currently get correct solutions for x >0 and complex solutions for x <1 when solved numerically for alpha = 1 while the analytical solution correctly gives only real answers. I think I am incorrectly numerically integrating this function. Can anyone show me how they would integrate this? My background is in Physics and I am only aware of some very basic numerical integration techniques.

Thanks for any help you can give me with this.
