WebAboutTranscript. Introducing intervals, which are bounded sets of numbers and are very useful when describing domain and range. We can use interval notation to show that a value falls between two endpoints. For example, -3≤x≤2, [-3,2], and {x∈ℝ -3≤x≤2} all mean that x is between -3 and 2 and could be either endpoint. 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.
