By the chain rule, the first derivative is
We have
so that
The second derivative is
where is a function of ; denote it by . Then by the chain rule,
Since
we end up with
The curve is concave upward whenever the second derivative is positive. We have this for
We have for where is any integer; for the given interval, this happens at . For , we have , while for , we have ; it's the latter that we care about, since over this interval we have .
