Best ResponseYou've already chosen the best response.0wht do u think??? @itsmeeQUENNIE i first of all used substitution and then used the ILATE rule.. and thts lengthy

Best ResponseYou've already chosen the best response.0i think ...i will use the LIATHE.. and yeah.. you're right.. it's lengthy...

Best ResponseYou've already chosen the best response.0the suppose e^x = u so e^x dx = du dx = du/(e^x)

Best ResponseYou've already chosen the best response.0i didn't get tht....wht do u mean???

Best ResponseYou've already chosen the best response.0why you let u = e^x, instead of letting u = cos e^x ... it is in the rule, right? the LIATHE!

Best ResponseYou've already chosen the best response.0u can even apply e^x = u so cos(e^{x}) = cos(1/u) so the integral would be \[\int\limits u^3 \cos(\frac{ 1 }{ u }) du\]

Best ResponseYou've already chosen the best response.0let v = u^3 dv = 3u^2du dw = cos (1/u) du w = ???? > i don't know the answer. :3

Best ResponseYou've already chosen the best response.0hold on the integral is \[\int\limits u^3 \cos \frac{ 1 }{ u } du\] first function is u^3 and second function is cos(1/u)

Best ResponseYou've already chosen the best response.0see \[\int\limits u~v ~~dx = u~(\int\limits~v~dx)  \int\limits ({\frac{ du }{ dx } \int\limits v~dx}) ~dx\]

Best ResponseYou've already chosen the best response.0u is the first function and v is the second function

Best ResponseYou've already chosen the best response.0my head is aching. waah! how to use the LIATHE again???

rishavraj

Best ResponseYou've already chosen the best response.0i think LIATHE is same as ILATE

Best ResponseYou've already chosen the best response.0when i was in 2nd yr college... my prof taught the LIATHE in my integral calculus subject... L  for logarithmic, I  for inverse, A  for algebraic, T  for trigonometric, H  for hyperbolic and E  for exponential...

Best ResponseYou've already chosen the best response.0i don't know how to do that.. it's too complicated for me...

Best ResponseYou've already chosen the best response.0see u^3 is first function and cos(1/u) is second so hold on i m gonna upload a pic
