Series

4.1 Introduction

4.1.1 Definition

In general a series sn is defined as a sum of a given number of terms ai such that

sn=a1+a2+...an=i=1nai

If n = , the series is said to be infinite series. If n is finite, it is said to be a finite series.

4.1.2 Convergence

In most practical applications, a series will have to be evaluated up to a given upper bound n. The higher this bound is chosen, the more exact the solution, but also the more time-consuming, complicated and computationally expensive the solution will become. Therefore a suitable trade-off for n must be found.

However, some of the more important series actually sum up to ...
