Lets first briefly define summation notation. Up to a naturalbreak point in the expression. Sigma notation enables us to write a sum with many terms in the compact form The Greek letter capital sigma corresponding to our letter S stands for sum The index of summationk tells us where the sum begins at the number below the symbol and where it ends at the number.

If fi represents some expression function involving i then has the following meaning.
A variable called the index of summation is written below the sigma.
The summation sign S instructs us to sum the elements of a sequence. The i part underneath the summation sign tells you which number to first plug into the given expression. An explicit formula for each term of the series is given to the right of the sigma. A typical element of the sequence which is being summed appears to the right of the summation sign. Summation notation is often known as sigma notation because it uses the Greek capital letter sigma latexsumlatex to represent the sum. Solve sum_k0n k2 5.
