enter image description here

The image shows the array (W) I'm trying to integrate. It gives the following errors: 1. NIntegrate::ncvb 2. NIntegrate::slwcon

I tried excluding the singularity points; adjusting the accuracy goal, working precision, min recursion and max recursion but nothing seems to eliminate the errors.

I'm using Mathematica 11.1. Any ideas what's wrong?

  • $\begingroup$ People here generally like users to post code as Mathematica code instead of images or TeX, so they can copy-paste it. It makes it convenient for them and more likely you will get someone to help you. You may find this this meta Q&A helpful $\endgroup$ – Michael E2 Oct 6 '17 at 10:32
