Webb17 aug. 2014 · Simpson's Rule uses quadratics (parabolas) to approximate. Most real-life functions are curves rather than lines, so Simpson's Rule gives the better result, unless the function that you are approximating is actually linear. Simpson's Rule requires that the data set have an odd number of elements which gives you an even number of intervals. can frogs spawn in normal swampsWebbSimpson’s Rule However, this problem can be alleviated by dividing larger intervals into smaller sub-intervals over which Simpson’s Rule will continue to work well.
