Comment (by nbruin):
Finding that there's a local max at x=pi/4 is of course just a freshman's
calculus exercise. I don't think this test is very good, though, because
there is another local max at x=9/4*pi, which also lies in the interval
(0,8). So you could get a wildly different answer that isn't wrong.
Shortening the interval to (0,7) would do the trick. Or is this test for
something in particular?
