8 3  Area between Two Curves
Intuitively, true in the sense of Leibnitz, integration is the act of calculating the area by
cutting the region into a large number of small strips of elementary area and then
adding up these elementary areas Suppose we are given two curves represented by
y = f (x), y = g (x), where f (x) ≥ g(x) in [a, b] as shown in Fig 8 13
