Question: The following:
(a) Find f' and f".
(b) Find the critical points of f.
(c) Find any inflection points.
(d) Evaluate f at the critical points and the endpoints. Identify the global maxima and minima of f.
(e) Sketch f. Indicate clearly where f is increasing or decreasing, and its concavity.
f(x) = x + sin x (0 ≤ x ≤ 2Π)
