Summation problems with solutions

By | September 17, 2011

Series is the sum of the terms of a sequence. The operation of getting this sum is called summation. A series can be represented in a compact form, called summation notation or sigma notation. The Greek capital letter sigma, , is used to indicate a sum. In this post, Mr. Frederick Koh shares an example of a task involving summation which he believes can help advanced level students appreciate summation notation. Mr. Koh says:

Many students get thoroughly irked by the sigma notation and reconciling it properly with the notion of mathematical sequences, so I shall put forth a detailed worked example to demonstrate how one must be flexible in obtaining the required solutions.
