Sigma Notation of a Series A series can be represented in a compact form, called summation or sigma notation. The Greek capital letter, ∑ , is used to represent the sum. The series 4 + 8 + 12 + 16 + 20 + 24 can be expressed as ∑ n = 1 6 4 n . The expression is read as the sum of 4 n as n goes free word to pdf acrobat converter For each of the following, use sigma notation and the appropriate summation formulas to evaluate the net signed area between the graph of f(x) and the x-axis on the given interval.
5.2: Sigma Notation Sigma Notation enables us to write a sum with many terms in the compact form: Xn k=1 a k = a 1 +a 2 + +a n 1 +a n: This notation has three main parts.
Sigma / Summation Notation Summation is something that is done quite often in mathematics, and there is a symbol that means summation. That symbol is the capital Greek letter sigma, and so the notation is sometimes called Sigma Notation instead of Summation Notation.
Description. The summation notation is a way to quickly write the sum of a series of functions. It is also called sigma notation because the symbol used is the letter sigma of the Greek alphabet.
