1. The problem statement, all variables and given/known data using the following definition: ln x = [tex]\int dx/x[/tex], give best possible upper and lower estimates of ln n, n a positive integer. then, use this result to show that the limit of the function as n approaches infinity is infinity. 2. Relevant equations -- 3. The attempt at a solution Unfortunately I have no idea what to attempt -- I don't know how to find estimates, and I'm not really sure what that means -- this is for a history of math class so I have no textbook context to look though either. Any explanations/tips would be very helpful, thanks!
