Question

can anyone tell me what is "L-Hospital's rule" in finding the limits of a function?

Answer 1

Is it anything like L-Hopital's rule? :)

Answer 2

l'hopital's rule states that
lim x->a of f(x)/g(x) = lim x->a of f'(x)/g'(x)

keep in mind that this means that the original function must be in fraction form. If not, the rule cannot be used.

Answer 3

\[\lim_{x \rightarrow a} f(x)/g(x) = \lim_{x \rightarrow a} f'(x)/g'(x)\]

thats a bit more clear i think. L-hopital's rule is used is used when the original limits yields one of the indeterminable forms. the fuction must be in the form of a fraction in order to apply the rule.

Answer 4

L-hospital,s rule is used when the fraction become" 0/0" or "infinite/infinite" after putting the limit.
we can apply l hospitals law more then once in a limit .
