# How do you know when to use L'hospital's rule twice?

You typically use L'Hôpital's Rule twice when applying it once doesn't yield a determinate form, such as 0/0 or ∞/∞, and the resulting limit still doesn't provide a definitive answer after the first application. If applying L'Hôpital's Rule once leads to another indeterminate form, then applying it again might help resolve the limit.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- Find the values of #x# for which the following series is convergent?
- Is the sequence #a_n=(1+3/n)^(4n)# convergent or divergent?
- How do you use the integral test to determine if #sum_(n=2)^oo 1/(nsqrtlnn)# from #[2,oo)# is convergent or divergent?
- How do you apply the ratio test to determine if #Sigma (3^n(n!))/(n^n)# from #n=[1,oo)# is convergent to divergent?
- How do you find the sum of #ln ( 1 + 1 / (2^(2^n)) )# from n=0 to infinity? Thanks!?
