We haven’t picked any specific K, but we know that b is always less or equal than K; again, this is because we defined b as a substitution for h - g, the delta between two indices in a sequence of K + 1 elements. Therefore, the expression in the denominator — K · b — involves multiplying b by a value that’s equal or greater than b. In effect, we have proof that for any real r, some a / b that satisfies ε
