Another solution I’ve seen is to use the Wingdings font for symbols. In other words, “Bring all the elements together but discard duplicates”.

Symbol font – Unicode alternatives for Greek and special characters in HTML. The caret is usually an indicator of two things: 1. that the column is sorted vs not sorted, and 2. the direction of the sort (asc vs desc).

The letter v won’t quite cut it. With reference to the original question, from the view of set theory, the word “union” relates to the ‘∪‘ symbol; and the word “intersection” relates to the ‘∩’ symbol. However, it usually represents the exponentiation operation. When writing on paper, or when the text editor supports superscript, the exponent is shown as a superscript. A powerful option – and one which also boosts creativity – is designing your own characters using box drawing characters. The union of sets ‘A’ and ‘B’ is the set containing the unique elements found in either set ‘A’ or set ‘B’, or both.

The approach which relates most closely to the question involves set theory. In particular I would like to add an unique class to each item like. javascript – How to get relative image coordinate of this div? Expert Opinion, Hydrate On Cactus Water For These 7 Benefits, Symbol font – Unicode alternatives for Greek and special characters in HTML, Intertextuality – All Texts are Part of a Matrix of Utterances, Introducing the Factorial: the Exclamation Mark of Math. From the example statements, “A∨B”, “A∨C” and “B∨C” are all true. In set theory, intersection and union are shown by ‘∩’ and ‘∪‘. I did subscript capital & bolded V. It works perfectly (although it takes some effort, if it needs to be done repetitively), You might consider using Font Awesome instead of using the unicode or other icons, The code can be as simple as (a) including font-awesome e.g. These are used in mathematical logic. Image by JRS. Our reader’s question is: “There are two sets of symbols for ‘union’ and ‘intersection’. Wood, Alan. javascript – window.addEventListener causes browser slowdowns – Firefox only. →. The “V” symbols in the reader’s question are ∨ and ∧, which mean “Logical Or” and “Logical And.” The ∧ is a capital Greek Lambda. Your email address will not be published. Wolfram Mathematica Documentation. The intersection of sets, “A∩B” has even less to do with a logical “or” (‘∨‘) operation. ⓘ Help or Why. phpunit mock method multiple calls with different arguments, © 2014 - All Rights Reserved - Powered by. However, “X or Y”, or “X∨Y”, is false if and only if both ‘X’ and ‘Y’ are false. A∪B={a, b, c, d, e, f, i, o, u, y}. In other words, to create an intersection, only select elements found in both original sets, which are the duplicates discarded by the union operation. Math symbols can be confusing! Here’s one: ╲╱. ● Leave a comment. I already have the basic script done to sort a given table on a given column in a given direction, and it works well as long as the table is limited by certain conventions we follow here. \ ♕ That has a lot fo arrows. (1997-2010). (2012). The caret symbol, ‘^’, might be mistaken for lambda, ‘Λ’. Symbols are everywhere in math, but do you know what they mean? Our reader’s question also asked about ‘V’ and upside-down ‘V’, ‘Λ’ or Lambda. Whatever order the original developer used in the database query is what you’re stuck with. ⛹ “X∨Y” is true if either ‘X’ or ‘Y’ is true, which includes the situation where both ‘X’ and ‘Y’ are true. However, “AΛB” and “BΛC” are both false. “X∨Y” is true if either ‘X’ or ‘Y’ is true, which includes the situation where both ‘X’ and ‘Y’ are true. (b) making a button such as .
