Mathematica Non-integrable multiple integrals for Mathematica

Click For Summary
The discussion revolves around evaluating complex multiple integrals in Mathematica, particularly when faced with "non-integrable" functions. The user, Anna, struggles with coding the integration process and seeks help to generate a final array of numerical values for varying time parameters. A respondent, Bill, suggests using NIntegrate for efficiency and emphasizes the importance of verifying results for accuracy. Anna acknowledges the advice and expresses a desire to simplify her approach while exploring further problems involving similar integrals. The conversation highlights the challenges of numerical integration and the need for clarity in coding strategies within Mathematica.

You probably have a division by 0 somewhere. Look at your variable j and see what happens near 0. Possible solutions are to interpolate the inverse of the original equation, or to simply avoid 0.
