What is a partial sum of an infinite series?

Answer 1
A partial sum #S_n# of an infinite series #sum_{i=1}^{infty}a_i# is the sum of the first n terms, that is, #S_n=a_1+a_2+a_3+cdots+a_n=sum_{i=1}^na_i#.

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.
