Find the limit of ln(n)/ln(n+1) as n--> infinity

In summary, the limit of ln(n)/ln(n+1) as n approaches infinity is always equal to 1 and can be calculated using methods such as L'Hopital's rule, the Squeeze theorem, or properties of logarithms. It is closely related to the natural logarithm function and is not affected by the base of the logarithm.

can someone help me find the lim as n approaches infinity of

ln(n)/ln(n+1)

I used L'HOP so it became (1/n)/(1/n+1) -- as this approaches infinity, it's 0/0, and this confuses me. What am I doing wrong?

What happens if you simplify the complex fraction

[tex]
\frac{\dfrac 1 n}{\dfrac 1 {n+1}}
[/tex]

before you evaluate the limit?

FAQ: Find the limit of ln(n)/ln(n+1) as n--> infinity

1. What is the limit of ln(n)/ln(n+1) as n approaches infinity?

The limit of ln(n)/ln(n+1) as n approaches infinity is equal to 1. This can be shown by using the L'Hopital's rule or by using the fact that as n approaches infinity, ln(n) grows much faster than ln(n+1), making the numerator and denominator approach the same value.

2. Can the limit of ln(n)/ln(n+1) as n approaches infinity be undefined?

No, the limit of ln(n)/ln(n+1) as n approaches infinity is always defined and equal to 1. This is because ln(n) and ln(n+1) both approach infinity as n approaches infinity, and when dividing two infinities, the result is always 1.

3. How is the limit of ln(n)/ln(n+1) as n approaches infinity related to the natural logarithm function?

The limit of ln(n)/ln(n+1) as n approaches infinity is closely related to the natural logarithm function. In fact, it can be rewritten as ln(n+1)/ln(n), which is the inverse of the natural logarithm function. This means that as n approaches infinity, the ratio of ln(n)/ln(n+1) approaches the inverse of the natural logarithm of n.

4. Can the limit of ln(n)/ln(n+1) as n approaches infinity be calculated using other methods besides L'Hopital's rule?

Yes, besides using L'Hopital's rule, the limit of ln(n)/ln(n+1) as n approaches infinity can also be calculated using other methods such as using the Squeeze theorem or by using the properties of logarithms.

5. Is the limit of ln(n)/ln(n+1) as n approaches infinity affected by the base of the logarithm?

No, the limit of ln(n)/ln(n+1) as n approaches infinity is not affected by the base of the logarithm. This is because as n approaches infinity, the base of the logarithm becomes insignificant compared to the value of n, resulting in the same limit of 1 regardless of the base used.
