cristo said:In what context it this? The two are equivalent, so it probably just means that. But, unless you provide the specific context (a question, say) then it will be difficult to guess.
The symbol "∑" represents the summation or addition of a series of numbers or terms. It is commonly used in algebra and calculus to indicate the total of a set of values or the sum of a sequence of numbers.
The symbol "≠" is read as "not equal to" and is used to show that two quantities are unequal or have different values. It is the mathematical equivalent of the "!=" symbol in computer programming.
The symbol "√" is called the radical symbol and is used to indicate the square root of a number. It is the inverse operation of squaring a number and is denoted as "√x" or "x^(1/2)".
The symbol "π" is the Greek letter pi and is used to represent the mathematical constant which approximates to 3.14159. It is commonly used in geometry, trigonometry, and calculus to represent the ratio of a circle's circumference to its diameter.
The symbol "∞" represents infinity, which is a concept used in mathematics to indicate something without an end or without limits. It is commonly used in calculus to represent the concept of limits and in algebra to represent an infinitely large value.
