answer:
Often mathematical formulae require the addition of many variables Summation or sigma notation is a convenient and simple form of shorthand used to give a concise expression for a sum of the values of a variable. Let x1, x2, x3, … xn denote a set of n numbers. x1 is the first number in the set.
Sigma notation is a method used to write out a long sum in a concise way. ... use rules to manipulate sums expressed in sigma notation.
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 6∑n=14n . The expression is read as the sum of 4n as n goes from 1 to 6 .
denote a set of n numbers.
Step-by-step explanation:
Sigma is fun to use, and can do many clever things. Learn more at Sigma Notation.
