Webf(x) = cos2 x−2sinx, 0 ≤ x ≤ 2π. (a) Find the intervals on which f is increasing or decreasing. Answer: To ﬁnd the intervals on which f is increasing or decreasing, take the derivative of f: f0(x) = 2cosx(−sinx)−2cosx = −2cosx(sinx+1). Since sinx+1 ≥ 0 for all x, we see that the sign of f0(x) is the opposite of that of cosx.

WebOn the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f(x) = 5x + 1, then the slope is just 5 everywhere, so f'(x) = 5. Then f''(x) is the slope of a horizontal line--which is 0. So f''(x) = 0.
