Homework Help: calculus

Posted by James on Sunday, November 14, 2010 at 11:48pm.

Find all relative extrema and points of inflection of the function:

f(x) = sin (x/2)

0 =< x =< 4pi

=< is supposed to be less than or equal to.

I can find the extrema, but the points of inflection has me stumped. The inflection point is (2pi,0) but shouldn't there be inflection points on x=0 and x=4pi as well?
