can those people plz explain what is it that makes

??

If you were not such a crank, you could get
explanations. As it is,
ponder on lim (x\to infinity) ln(x^2+sin
(x^3))/sqrt(x+cos x). Is really
L'Hospital or Taylor such a good idea ?

since x goes to oo we can disregard the sine and cosine.

then we have 2*ln(x)/sqrt(x).

and both l'Hospital and Taylor can be applied here.




i dont see a downside of l'hospitals rule ?

and i was quite amazed to read that on a mathforum
from even relative regular posters.
