    Exclamation [SOLVED] LIATE: is it reliable?

    My friend told me that when you are taking Integration by Parts that you can use the Acronym "LIATE" (Logarthym Inverse Algrebra Trigonometry Exponential)
    where you let u = something and dv = something, and which ever comes first in that acronym comes first as well respectively. But I have had instances where it doesnt work which results in me spending an hour (seriously ) trying to solve it.

    Please if someone knows certian exclusions from this rule...do tell! O yeah and I have a quiz this Friday so I might need the help quite fast

    But if noone knows its okay, I dont really think a lot of people know about it, But if you do know...please do tell!

    This is the first time I have heard of this mnemonic, and I've never had any
    problems with integration by parts. Perhaps you should consider trying
    for better understanding and intuition rather than rely on such crutches.
