Nov 7, 2015 · 19. "Much less than" is a qualitative assessment of comparative inequality. a ≪ b means that a is not only less than b, but muchly so by some convention. That convention is fairly arbitrary, or rather contextual; there is no fixed quantitative basis. Sometimes it is based on additive position, sometimes on multiplicative magnitude.

It tells us that the given variable is either greater than or equal to a particular value. For example, if x ≥ 3 is given, it means that x is either greater than or equal to 3. It defines a range of values that x can take which starts from 3 and goes up till infinity. 1. In mathematics, a representation is a very general relationship that expresses similarities (or equivalences) between mathematical objects or structures.Abbreviation. The phrase “if and only if” is used commonly enough in mathematical writing that it has its own abbreviation.

Basically, the definition states that "it is a collection of elements". These elements could be numbers, alphabets, variables, etc.t. e. In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base 10 of 1000 is 3, or log10 (1000) = 3. In general mathematics, lowercase σ is commonly used to represent unknown angles, as well as serving as a shorthand for "countably", whereas Σ is regularly used as the operator for summation, e.g.: In statistics, σ represents standard deviation of population or probability distribution (as opposed to lowercase mu or μ, used for mean).Mathematical Symbols Mathematical symbols are used to perform various operations.

It is borrowed from computer programming: it means that the item on the left hand side is being defined to be what is on the right hand side. For example, y:= 7x + 2 y := 7 x + 2. means that y y is defined to be 7x + 2 7 x + 2. This is different from, say, writing. 1 =sin2(θ) +cos2(θ) 1 = sin 2 ( θ) + cos 2 ( θ) Mean is nothing but the average of the given set of values.

As mathematics developed over the course of history, mathematicians needed more symbols to represent the numbers, functions, sets, and equations that were coming to light. Because most scholars had some understanding of Greek, the letters of the ancient Greek alphabet were an easy choice for these symbols.

increment: An increment is a small, unspecified, nonzero change in the value of a quantity. The symbol most commonly used is the uppercase Greek letter delta ( ).

To calculate it: • add up all the numbers, • then divide by how many numbers there are. Example: what is the mean of 2, 7 and 9? Add the numbers: 2 + 7 + 9 = 18 Divide by how many numbers (i.e. we added 3 numbers): 18 ÷ 3 = 6 So the mean is 6Sometimes in math we describe an expression with a phrase. For example, the phrase. " 2 more than 5 ". can be written as the expression. 2 + 5 .

In mathematics, the greater than symbol is a basic mathematical symbol which is used to represent the inequality between two values. The symbol used to represent the greater than inequality is “ > “. This is the universally adopted math symbol of two equal length strokes joining in the acute angle a t the right.You know what the equal symbol means and looks like. If a = b, then a and b are equal, (8 = 8). To learn about ordering real numbers, think about it this way. If a real number b is greater than a real number a, their relationship would look like this: −2 > −5 since −2 is to the right of −5 on the number line.The greater than or equal to symbol is used to represent inequality in math. It tells us that the given variable is either greater than or equal to a particular value. For example, if x ≥ 3 is given, it means that x is either greater than or equal to 3.
