So can the tabular method be used when we’d integrate by parts one time? Like how many times “n” at a minimum does the integration by parts have to repeat in order to be used correctly?
Typically when I use the DI method, when you differentiate polynomials, it’ll end up reaching zero so that’s why it’s best to differentiate polynomials that can be reduced to zero, and integrating the other function (which is easy if it’s trig or an exponential), But I’m not so sure about differentiating non polynomials. A teacher taught me that you usually “stop” when if you look horizontally (not diagonally) in the table, you end up BACK at the integral that you started at, that’s when you can stop and say that whatever you’ve obtained in the table is your answer (just without the repeat of the same integral) He also taught me to stop when you find integrating or differentiating the function too easy but I’ve yet to encounter what that possibly means so take that one very lightly 😅 Hope this helps you man, have a nice time learning
Great question! If you search around, you'll find both ILATE and LIATE used as common acronyms. Both can be used very reliably. In the case of an integral with an inverse trig and logarithm, both can usually be used (although that'll be a tough integral!). However, if you find yourself having trouble using either ILATE or LIATE, you can always try the other one to see if it's a bit easier!

Don't we choose logarithm over inverse signs and not the othe way round
