Hi

I have a problem I hope you can help me solve. I am working with the error function. I have looked at

some papers involving all the combinations of this function with other functions and their integrations, but this particular model is not listed in there:

int{erf(a*sqrt((x-a)^2+b^2))))/((x-a)^2+b^2)} with respect to x

I would really appreciate it if you let me know which formula you think I should use to derive this integral.

Many thanks
