What is sigma notation?
Sigma notation concept means summarizing all conditions and using three parts to create mathematical commands such as ∑ i and i . The Greek letter ∑ is the Sumance operator and means the sum of all, I is called the index number and i refers to a number of terms to be added together. This mathematical notation is used to compact equations in which all terms are required. For example, it can be used to show the addition of hours of all employees in the company. If a i hours worked with a particular employee and exist by employees n , then ∑ i A a a and and and a and and and and a and and and a and and
understanding of associative, diCentral and commutative properties allow more use of this mathematics. Associative and commutative properties will allow any number to multiply by all conditions. Instead of performing multiplication for each term, this can be done once at the end by the sum of all conditions. If each employee has obtained k per hour, Sigma notation is written compactly as to ∑ i and i . The distribution feature changes the sum of two series of numbers into two Sigma notations.
In many common situations, a Sigma notation, often referred to as a summary with a summary, can be used. For example, it can be used to calculate the sum of deposits for a bank account. Banks add up all deposits and selections to determine the current balance. Food intake shows all items to be added and deducted to calculate the cash register. All these examples can be written in a short formula.existsAlso many complicated examples of use of notation Sigma. Many university students need a sigmar notation to solve difficult problems. Computer programmers use Sigma notation for finance, business and game software. Scientists often use it in statistical analysis of their experiments.
The history of notation Sigma was changed by Carl Friedrich Gauss at the end of the 18th century. He was asked to calculate the sum of the first 100 integers. He returned with the correct answer, 5050. He realized the new sentence that ∑ i and i is the same as adding the first and last numbers, such as 100+1 then 99+2, which always gives the same answer, 50 times. He was a small child when he discovered this sentence and became a renowned mathematician.
