Question

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

amistre64 · Answer

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

anonymous · Answer

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.

anonymous · Answer

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

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.

anonymous · Answer

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 .
