The symbol can be represented in the Greek letter sigma “∑”. The lower number denotes the lower limit of the index (it denotes the summation begins) whereas the upper number denotes the upper limit of summation (it denotes the summation ends). While using summation notation, the variable written below the sigma is called the index of summation. The most common technique of writing infinite numbers of terms in a sequence is called summation notation (a.k.a sigma notation). In this article, we will discuss the basic definition, formulas, properties, and how to find them. Summation notation is widely used in various fields of mathematics, including calculus, statistics, and number theory, as well as in physics and engineering. This is particularly useful in computer programming and other fields where iterative processes are used to solve complex problems. The sequence is usually defined by an index variable, such as (i or n), and a lower and upper limit.Īnother benefit of summation notation is that it enables mathematicians to express recursive formulas and algorithms concisely and elegantly. The notation uses the symbol “∑” which is the Greek letter sigma that represents the sum of a sequence of terms. The notation was first introduced by the Swiss mathematician Leonhard Euler in the 18th century and later popularized by Carl Friedrich Gauss. Summation notation is also known as sigma notation in mathematics, shorthand is used to represent the sum of a sequence of numbers. ![]()
