Problem 3:

(a) Find the area between f(x) = 1/x and the x-axis for 1 ≤ x ≤ 10, 1 ≤ x ≤ 100, and

1 ≤ x ≤ A. What is the limit of the area for 1 ≤ x ≤ A as A→∞?

(b) Find the volume swept out when the region in part (a) is revolved about the x-axis for 1 ≤ x ≤ 10, 1 ≤ x ≤ 100, and 1 ≤ x ≤ A. What is the limit of the volumes for 1 ≤ x ≤ A as A → ∞ ?
