Content preview: Hello, in this case, the general idea is to split your domain in three parts: SUM(-infinity,+infinity)=SUM(-infinity,a)+SUM(a,b)+SUM(b,+infinity), with -infinity < a < b < +infinity . Then, by figuring out an appropriate changement of variable, you may be able to reduce your three integrals into three finite integrals to which you can easily apply the function exposed in the Chapter "Numerical Integration".
