## anonymous 5 years ago What are the criteria for using L'Hopital's rule?

1. Mini

0/0

2. Mini

0*inf

3. Mini

uh 0 - inf

4. anonymous

the limit must exist

5. anonymous

As Mini was saying, it cannot be an indeterminate form.

6. Mini

0/0 is the easiest one to see, then u can just do it on top and bottom, but dont confuse it with the quotient rule! thatll suck!

er Scratch what I said last: \lim_{x\to c}{f(x)} = \lim_{x\to c}g(x) = 0 or \lim_{x\to c}{f(x)} = \pm\lim_{x\to c}{g(x)} = \pm\infty. And suppose that \lim_{x\to c}{\frac{f'(x)}{g'(x)}} = L. Then \lim_{x\to c}{\frac{f(x)}{g(x)}}=L.

thats so confusing to try to read on this

9. Mini

qriy just post the equation it might be easier

Does Limit of (x-4)/(x+4)^2 with x->-4 fit the criteria for L'Hopital?

Some of the situations that call for Lhopital$\infty/ \infty$$\infty-\infty$$1^{\infty}$$\infty ^{0}$$0^{\infty}$$0\infty$
