5. (10 points) Set up, but DO NOT EVALUATE, an integral for the volume of the solid obtained by rotating the given region about the specified line. a. Region bounded by y = tan x, y = 1, x = 0 rotated about the x-axis b. Region bounded by y = x, y = 4x2, rotated about the y-axis c. Region bounded by y = 0, y = sin x, x = 0 and x = n; rotated about y = -2
