4.6 Numerical Integration Trapezoid and Simpson’s Rules
Trapezoidal Rule To estimate the definite integral, we will divide the Interval into “n” trapezoids.
The Trapezoidal Rule Let f be a continuous function on [a,b]. Then the Trapezoidal Rule for estimating the definite integral is given by
Use the Trapezoid Rule to approximate the definite integral for the given “n”.
Use the Trapezoid Rule to approximate the definite integral. Compare results when n=3 and n=6
Simpsons Rule (with an even “n”) Let f be a continuous function on [a,b]. Simpson’s Rule for estimating the definite integral is given by
Use Simpsons Rule to approximate

Numerical Integration In general, a numerical integration is the approximation of a definite integration by a “weighted” sum of function values at discretized.
