Problem 86AE

Riemann sums to integrals Show that $$L=\lim _{n \rightarrow \infty}\left(\frac{1}{n} \ln n !-\ln n\right)=-1$$ in the following steps.

a. Note that $$n !=n(n-1)(n-2) \cdots 1$$ and use ln (ab)=ln a + ln b to show that $$L=\lim _{n \rightarrow \infty}\left[\left(\frac{1}{n} \sum_{k=1}^{n} \ln k\right)-\ln n\right]=\lim _{n \rightarrow \infty} \frac{1}{n} \sum_{k=1}^{n} \ln \left(\frac{k}{n}\right)$$

b. Identify the limit of this sum as a Riemann sum for $$\int_{0}^{1} \ln \ x \ d x$$. Integrate this improper integral by parts and reach the desired conclusion.
