Webof 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. Thus, f0(x) < 0 (meaning f is decreasing) on the intervals [0,π/2),(3π/2,2π] and f0(x) > 0 (meaning f is increasing) on the intervals (π/2,3π/2). (b) Find the local maximum and minimum values ... WebIf F is an antiderivative of f, and the function f is defined on some interval, then every other antiderivative G of f differs from F by a constant: there exists a number c such that () = + for all x. c is called the constant of integration.
