Unformatted text preview: Area under curves Consider the curve y = f(x) for x ∈ [a, b] The actual area under the curve is 83.60 units2 . The approximate area is the sum of areas of trapezoidal strips. Number of strips: y y = f( x ) 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 Approximate area: 0 a bx 83.53 83.52 83.51 83.50 83.49 83.47 83.46 83.43 83.41 83.37 83.33 83.26 83.18 83.05 82.86 82.55 82.00 80.85 77.79 63.59 units2 Area under curves As the number of strips, n, becomes large, the approximate area approaches the actual area under the curve. The actual area under the curve is 83.60 units2. The approximate area with 20 trapezoidal strips is 83.53 units2. y y = f( x ) 0 a bx ...
