I'm not sure how the LIATE rule doesn't work? You can choose to integrate exponential first then trig or alternatelyView attachment 35690
I rely on the LIATE and realised it does not work here? Can someone clarify....
is it possible for u to recall the full form of liate as ive forgottenLIATE is the order for the functions that are best to integrate. cosx is a Trig function therefore is better to integrate, while e^2x is Exponential so better to differentiate.
Personally I remember the order DETAIL which is a similar conceptis it possible for u to recall the full form of liate as ive forgotten
aye thx a lot broPersonally I remember the order DETAIL which is a similar concept
Differentiate to the following priority;
Exponentials
Trig functions
Algebra (polynomials)
Inverse Trig functions
Logarithms
ye fair it does work - the worked sols seemed rigged as they let u = cos instead.......I'm not sure how the LIATE rule doesn't work? You can choose to integrate exponential first then trig or alternately
I don't really go off LIATE since integrating the exp. here feels a bit messy dealing with fractions and I'd rather just deal with whole numbers. You'll get the same thing. Personally I'd say use LIATE as a guide but don't be bounded by it, use your own intuition to foresee which one's going to be more convenient to go through with IBP, it helps reduce algebraic errors.
