Let n ∈ N. Then, the derivative of the polynomial (x n) ∈ Q[x] is d dx(x n) = n ∑ k = 1( − 1)k − 1 k ( x n − k). My proof relies on three identities for binomial coefficients. The first is the famous Chu-Vandermonde identity: Theorem 2. Let n ∈ N.If lim n→∞an = 0 lim n → ∞ a n = 0 the series may actually diverge! Consider the following two series. ∞ ∑ n=1 1 n ∞ ∑ n=1 1 n2 ∑ n = 1 ∞ 1 n ∑ n = 1 ∞ 1 n 2. In both cases the series terms are zero in the limit as n n goes to infinity, yet only the second series converges. The first series diverges.To put it another way, the random variable X in a binomial distribution can be defined as follows: Let Xi = 1 if the ith bernoulli trial is successful, 0 otherwise. Then, X = ΣXi, where the Xi's are independent and identically distributed (iid). That is, X = the # of successes. Hence, Any random variable X with probability function given by1 Answer.
