comment Converge the sequence $\left(\left(1+\frac{1}{n}\right) \left(1+\frac{2}{n}\right)\cdots\left(1+\frac{n}{n}\right)\right)^{1/n}$
It looks like you applied the natural logarithm (and its rules) to the above expression to end up with a Riemann sum. Is this correct?

comment Intervals of Convex and Concave function
You correctly found the point where the second derivative of the function changes its sign. Now, what you call each half is irrelevant, really. However, if rain falls from above, then $x>\ln1/2$ will collect water because it is concave.
