How do you find the 6-th partial sum of the infinite series #sum_(n=1)^oo1/n# ?

Answer 1

The 6th partial sum of the infinite series ( \sum_{n=1}^{\infty} \frac{1}{n} ) can be found by simply adding the first 6 terms of the series:

[ S_6 = \frac{1}{1} + \frac{1}{2} + \frac{1}{3} + \frac{1}{4} + \frac{1}{5} + \frac{1}{6} ]

[ S_6 = 1 + \frac{1}{2} + \frac{1}{3} + \frac{1}{4} + \frac{1}{5} + \frac{1}{6} ]

[ S_6 = 1 + 0.5 + 0.3333 + 0.25 + 0.2 + 0.1667 ]

[ S_6 = 2.55 ]

Answer 2

#S_6=49/20#

Let's get a formula for the #kth# partial sum:
#S_k=sum_(n=1)^k1/n=1+1/2+1/3+...+1/k#
The #6th# partial sum is then obtained as follows:
#S_6=sum_(n=1)^6 1/n=1+1/2+1/3+1/4+1/5+1/6=49/20#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
