Rogawski Calculus Copyright © 2008 W. H. Freeman and Company Chapter 7: Techniques of Integration Section 7.1: Numerical Integration Jon Rogawski Calculus, ET First Edition

Rogawski Calculus Copyright © 2008 W. H. Freeman and Company The shaded area in Figure 1 cannot be calculated directly using a definite integral, since there is not an explicit antiderivative for Instead, we will rely on numerical approximation using the trapezoidal method

Rogawski Calculus Copyright © 2008 W. H. Freeman and Company If we divide the interval [a, b] into N even intervals, the area may be found using the Trapezoidal Rule

Rogawski Calculus Copyright © 2008 W. H. Freeman and Company As shown in Figure 3, the area of the trapezoidal segment is equal to the average of the left- and right- RAM areas. As shown in table one, by increasing the size of N, we can attain whatever degree of accuracy we may need.

Rogawski Calculus Copyright © 2008 W. H. Freeman and Company Figure 5 illustrates how a mid point estimate rectangle has the same area as a trapezoid where the top of the trapezoid is tangent to the curve at the midpoint of the interval.

Rogawski Calculus Copyright © 2008 W. H. Freeman and Company If we assume f ″ (x) exists and is continuous on our interval, we may use Theorem 1.

Rogawski Calculus Copyright © 2008 W. H. Freeman and Company Figure 6 shows how trapezoidal estimates for areas under curves are more accurate for those with small values of f ″.

Rogawski Calculus Copyright © 2008 W. H. Freeman and Company Figure 6 shows the points we would use in calculating T6 and M6 for an approximation to the area of the shaded region in Figure 8.

Rogawski Calculus Copyright © 2008 W. H. Freeman and Company Figure 10 illustrates how trapezoids provide an underestimate of areas under concave down curves and midpoints provide over- estimates. The opposite holds true for concave up curves.

Example, Page 424 State whether T N or M N overestimates or underestimates the integral and find a bound for the error. Do not calculate for T N or M N. Rogawski Calculus Copyright © 2008 W. H. Freeman and Company

Example, Page 424 Use the Error Bound to find a value of N for which the Error (T N ) ≤ 10 – 6. Rogawski Calculus Copyright © 2008 W. H. Freeman and Company
