Question:

Show that |L = lim - In n! – In n  in the following steps.

a. Note that n! = n(n - 1)(n - 2) · · · · 1 and use ln (ab) = ln a + ln b to show that (:ż--)- nk) = lim In- - Σnk k=1 L = lim In n n→0 N k=1

b. Identify the limit of this sum as a Riemann sum for Integrate this improper integral by parts and reach the desired conclusion.
