This program performs numerical integration using the Trapezoidal Rule and Simpson’s Rule, allowing users to approximate definite integrals for a given function over a specified interval.

integral (F, X, Start, End, Result) is the function that calculates the definite integrals. integral2/5 is a helper predicate and it exists only because if there was only one integral predicate, the ...
