  • The summation of the product of a constant with a variable is equal to the product of the constant with the summation of the variable.
  • The summation of the sum of two terms is equal to the sum of the individual summations.

Study Notes

Summation Notation Overview

  • A concise mathematical notation representing the sum of a sequence of terms.
  • Summation notation is typically denoted by the Greek letter Sigma (Σ).

Index of Summation

  • Represents the variable of summation; it indicates the position of each term in the sequence.
  • The index often starts at a specific value and increments by one until it reaches the upper limit.

Upper Limit of Summation

  • The maximum value that the index of summation can take.
  • It determines the total number of terms to be included in the summation.

Distributing a Constant

  • The property of summation that allows a constant factor to be factored out is known as the linearity of summation.
  • This property states that c * Σa_n = Σ(c * a_n), where c is a constant and a_n is the term being summed.

Term of the Summation

  • Represents each individual element or component being added together in the summation.
  • The term is typically defined by the index, such as a_i for i = 1 to n, indicating that each term corresponds to a different value of the index.
