4 sty 2016 · Simpson's Rule is a simple but powerful method for approximating signed area via "quadratic approximations". After a brief review of the "1-4-1" quadratic rule, Simpson's Rule is...
Use Simpson’s rule to approximate the value of a definite integral to a given accuracy. With the midpoint rule, we estimated areas of regions under curves by using rectangles. In a sense, we approximated the curve with piecewise constant functions. With the trapezoidal rule, we approximated the curve by using piecewise linear functions.
Simpson's rule is used to find the approximate value of a definite integral by dividing the interval of integration into an even number of subintervals. Learn Simpson's 1/3 rule formula and its derivation with some examples.
Example using Simpson's Rule Approximate `int_2^3(dx)/(x+1)` using Simpson's Rule with `n=4` . We haven't seen how to integrate this using algebraic processes yet, but we can use Simpson's Rule to get a good approximation for the value.
Figure 1: Simpson’s rule for n intervals (n must be even!) When computing Riemann sums, we approximated the height of the graph by a constant function. Using the trapezoidal rule we used a linear approximation to the graph. With Simpson’s rule we match quadratics (i.e. parabolas), instead of straight or slanted lines, to the graph.
