 OFFSET 1,1 COMMENTS The geometric integral of a function, f(x), from a to b is defined as lim_{dx->0} Product_{i=1..n} f(x_i)^dx, where n = (b - a)/dx and x_i is a number on the interval [a + dx*(i-1), a + dx*i]. The geometric integral can be shown to be equivalent to exp(Integral_{a..b} log(f(x)) dx).
