N * (1 1/2 1/3 1/4 1/n) Unlike the geometric series the harmonic series does not converge, but it diverges as we add more terms The partial sums of first n terms can be bounded above and below by ln n C , hence the time complexity of the entire algorithm is θ(n log n)Sep 28, 19 · Determine a formula for the sum 1 1/2 1/3 1/4 1/n?This is one of those questions that have dozens of proofs because of their utility and instructional use I present my two favorite proofs one because of its simplicity, and one because I came up with it on my own (that is, before seeing others do it it's known)
Question Find A (short) Formula For The Sum 1/1 2 1/2 3 1/n(n 1) = Sigma^n_k = 1 1/k(k 1);The partial sums form a convergent sequence 1, 2/3, 1, 4/5, 1, 6/7, The sequence converges to 1 Grouping pairs of successive terms leads to every other sum being omitted but does not change the fact of convergence, nor affects the limit itself The second series to consider is 1/1 2/3 2/3 3/5 3/5 4/7The general formula for the partial sums is, () 2 2 1 3 1 1 1 4 2 2 1 n n i s i n n = = = − − − ∑ and in this case we have, () 3 1 1 3 lim lim 4 2 2 1 4 n n n s n n →∞ →∞ = − − = The sequence of partial sums converges and so the series converges also and its value is, 2 2 1 3 1 4
