WebDiscrete functions have differences or divided differences and not derivatives. For example if f (n) = 2n^3 + 7n then the first forward difference is f (n+1) - f (n) and the first backward difference is f (n) - f (n-1). These are 2 (n+1)^3 - 2n^3 + 7 (n+1) - 7n = 6n^2 + 6n + 9 and 2n^3 - 2 (n-1)^3 + 7n - 7 (n-1).
