@Ji'anLi Also, I'm using V13.1. Integrate[] is updated probably in every new version of Mathematica. If you're using a different version, it might explain why the GenerateConditions -> False version takes more than a few seconds.

@Ji'anLi You're welcome. I would say that anything that takes 1100 sec. on a modern computer is doing a lot. The answer I linked shows how to get more information, but I would expect the output to be hundreds of pages. Most of the output will be impossible to understand without being familiar with the internal code. I'm not, and I wouldn't look into this any farther. I'd be satisfied with finding the Csc[5 t] factor above and thinking that's leading to difficulties.

The debugging techniques is really helpfull, I think I need to take a good look at it, so that to figure out what happened during the points process | |
