I. Area Under a Curve

1. If a function, f(x), is a curve graphed in the interval [a, b], then the area bounded by the curve, the x-axis, and the vertical lines containing the endpoints of the interval [a, b] may be approximated through the following:
   1. Rectangular methods
      1. Divide the interval into rectangles with equal width of

         b − a

         n

         .
      2. This results in n + 1 points on the x-axis.
      3. These points are x₀ = a, x₁ = a +

         b − a

         n

         , x₂ = a + 2

         	b − a
         	n

         , … , x_n = a + n

         	b − a
         	n

         .
      4. Find the sum of these n rectangles of equal width in the bounded region.
      5. Left-endpoint method
         1. The height of each rectangle is the vertical left side.
         2. The height of each rectangle is f(x_i) for 0 ≤ i ≤ (n – 1).
         3. The sum of these rectangle areas is

            b − a

            n

            [f(...
