symbol Σ
The symbol Σ (sigma) is generally used to denote a sum of multiple terms. This symbol is generally accompanied by an index that varies to encompass all terms that must be considered in the sum. For example, the sum of first whole numbers can be represented in the following manner: 1 2 3 ⋯.

The letter F with a hook (majuscule Ƒ, minuscule: ƒ) is a letter of the Latin script, based on the italic form of f; or on its regular form with a descender hook added. A very similar-looking letter, ⟨ʄ⟩ (a dotless j with a hook and a horizontal stroke), is used in the IPA for a voiced palatal implosive.
How to write a formula in sigma notation?
Writing this in sigma notation, we have Checking our work, if we substitute in our x values we have 2 (1)+2 (2)+2 (3)+2 (4)+2 (5)+2 (6)+2 (7)+2 (8) = 2+4+6+8+10+12+14+16 = 72 and we can see that our notation does represent the sum of all even numbers between 2 and 16.
How to calculate the Sigma of a series?
The series 4 + 8 + 12 + 16 + 20 + 24 can be expressed as 6 ∑ n = 14n . The expression is read as the sum of 4n as n goes from 1 to 6 .
What does the Sigma symbol mean in physics?
In physics, you will often come across terms like 2-sigma, 5-sigma, and so on. This is a further extension of the use of sigma for representing standard deviation. Sigma with a bigger number as a prefix signifies a relatively lesser deviation from a set value and vice versa.
