Derive the formula for pn k 1 k 2
WebApr 15, 2024 · Formula for ∑ k = 1 n k 2 k [duplicate] Closed 4 years ago. I'd also appreciate if someone could indicate some materials about this subject. In my answer here I show how to derive the formula for the related sum of ∑ k = 1 ∞ k p ( 1 − p) k − 1 = 1 p. WebProblem4(WR Ch 3 #11). Suppose an ¨0, sn ˘a1 ¯¢¢¢¯an, and P an diverges. (a) Prove that P a n 1¯an diverges. Solution. Assume (by way of contradiction) that P a n 1¯an converges. Then an 1¯an!0 by The-orem 3.23. Since an 6˘0, we can divide the top and bottom of this fraction by an to get 1 1 an ¯1! 0, which implies that 1 an! 1, which again implies that an!0.

WebSolutions to Problem Set 2 1. (MU 2.4; Jensen’s Inequality) Prove that E[Xk] ≥ E[X]k for any even integer k ≥ 1. By Jensen’s inequality, E[f(X)] ≥ f(E[X]) for any convex function f. If f is twice differentiable and its second derivative is non-negative, then f is convex. For f(x) = xk, the second derivative Web2 Suppose for some n ≥ 1 (a +b)n = Xn k=0 n k akbn−k.
