Question 1. Consider the function f(x) = x cos(x) in the interval [0,27]. Within the interval (0, 2), the critical points of f(x) are at x = 0.86 and x = 3.426. Also, the critical points of f'(x) are at x = 2.289 and z = 5.087. (a) Sketch the graph of f(x) in the interval [0, 2π]. Shadow the region bounded by the curve y = f(x) and the x-axis. (b) (c) Use the Fundamental Theorem of Calculus II to find the area of the shaded region in Part (a), i.e., c2π [²* |x cos(x)\da. Rotate the shaded region described in Part (a) around the z-axis to generate a solid. A cross-sectional region A(r) at a point x on the x-axis (the axis of rotation) is obtained by intersecting the solid with a plane perpendicular to the x-axis passing through x. Describe the shape of A(z) and determine the area of A(π).
