>>12332157>>12332185There are textbooks dedicated to all the methods of solving integrals. These are very niche textbooks because knowing these techniques isn't that useful nowadays but just find one from a good author and go with it. Cleo, due to her issues, probably just studied that shit 24/7 and could recall the techniques and apply them way faster than professors (who also have to juggle their careers and can't spend hours on online problems).
So just get a lot of free time and get autistic about integration. Plenty of books for that kind of stuff.
