- notation - What does := mean? - Mathematics Stack Exchange
What does := mean?where we are saying that the two sides are equal, but we are not defining "1" to be the expression " sin2(θ) +cos2(θ) sin 2 (θ) + cos 2 (θ) " Basically, some people think that there should be notational difference between saying "I define blah to be equal to blankety " and saying " blah is equal to blankety " So they use := for the first and = for the latter Usually
- Symbol for “such that” (not in set) - Mathematics Stack Exchange
Nobody should be using ∋ ∋ to mean "such that"; it is used in texts everywhere to mean ∈ ∈ but in the reverse direction (that's why the LaTeX code is "\ni" after all) I would argue ":" is the superior notation for set-building since (in most handwriting) it is the least likely to be confused with anything else (I, l, 1), hence being the most readable
- notation - Difference between ≈, ≃, and ≅ - Mathematics Stack . . .
In mathematical notation, what are the usage differences between the various approximately-equal signs "≈", "≃", and "≅"? The Unicode standard lists all of them inside the Mathematical Operators Block
- Much less than, what does that mean? - Mathematics Stack Exchange
What exactly does ≪ mean? I am familiar that this symbol means much less than but what exactly does "much less than" mean? (Or the corollary, ≫) On Wikipedia, the example they use is that 1 ≪ 9999999999 But my thought on that is that 10101011 ≪ 10101011 + 9999999999, based on the same logic But I am confused because the numbers are comparitively Logically, I am really kinda spent
- notation - Math Symbol for Where - Mathematics Stack Exchange
The use of natural language is often more effective when presenting an idea In my opinion the less often a symbol is used where a few words can go, the better That said, there are many places where symbols are useful and simplify matters The word "where" can often be replaced with "such that", and corresponding to this we have a few regularly used symbols For instance, in set builder
- notation - What do Subscripted numbers in an equation mean . . .
@Brian M Scott What does it mean when each subscript is non-numerical, and is exactly the same? I have an equation that has a value T (temperature in Kelvin), subscripted gamma It's used several times each the same way, no variation, and all other equations in the same family simply use T, unsubscripted What might that mean?
- notation - What is the mathematical symbol for range? - Mathematics . . .
An unsophisticated question from a neophyte: Given the numbers: $1,2,3,4,5$ What is the symbol for the range of the numbers? i e the lowest-highest number in the set For example, the min max
- notation - The best symbol for non-negative integers? - Mathematics . . .
The set of natural numbers {0, 1, 2, …} {0, 1, 2, …} is often denoted by ω ω There are two caveats about this notation: It is not commonly used outside of set theory, and it might not be recognised by non-set-theorists In "everyday mathematics", the symbol N N is rarely used to refer to a specific model of the natural numbers
