Save my name, email, and website in this browser for the next time I comment. In mathematical logic, the “and” and “or” operations are shown by ‘Λ’ and ‘V’. However, “X or Y”, or “X∨Y”, is false if and only if both ‘X’ and ‘Y’ are false. Let A={a, e, i, o, u, y} and B={a, b, c, d, e, f}. What is the relationship between these symbols, which we sometimes think of as ‘U’s and ‘V’s?”. 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). Want a down pointing “caret”? ▲

HTML, CSS, JavaScript? ♪ Accessed July 26, 2012. (1997-2010). The “V” symbols in the reader’s question are ∨ and ∧, which mean “Logical Or” and “Logical And.” The ∧ is a capital Greek Lambda.

In the case of sorting a caret isn't used unless a column has been sorted. The union of sets, “A∪B”, might be seen as taking all the elements of ‘A’ and also the elements of ‘B’; but that would not be the “and” (‘Λ’) of mathematical logic. One is the ∪ and the upside down ∩, and the other set is the ∨ and the ∧. The union of sets ‘A’ and ‘B’ is the set containing the unique elements found in either set ‘A’ or set ‘B’, or both. So let’s mind our Us and Vs, and their upside-down companions, in unions and intersections as well as logical functions. Questions: I created a custom menu called “sub-top-nav” and now I’d like to override the html output. phpunit mock method multiple calls with different arguments, Â© 2014 - All Rights Reserved - Powered by. I’d use a couple of tiny images. I did subscript capital & bolded V.

Wolfram Mathematica Documentation. An upside-down circumflex is called a caron, or a háček. Introducing Math Symbols for Union and Intersection, The Math Symbols from the Question about Union and Intersection, Programming Computers with “And” and “Or”, Summary of Mathematical Symbols for Intersection and Union, And and Or, Is There A Hangover Prevention Pill That Actually Works? Therefore the caret is not indicating "more" in a sort, and usually isn't displayed until after the user decides to sort a column.

The intersection of sets, “A∩B” has even less to do with a logical “or” (‘∨‘) operation. In other words, to create an intersection, only select elements found in both original sets, which are the duplicates discarded by the union operation. However, “AΛB” and “BΛC” are both false. (2012). (b) making a button such as . ∀ - for all - upside down A (u+2200) B - latin capital letter b (u+0042) В - deseret capital letter bee (u+10412) C - latin capital letter c (u+0043) Ↄ - roman numeral reversed one hundred (u+2183) D - latin capital letter d (u+0044) - left half black circle (u+25d6) E - latin capital letter e (u+0045) Ǝ - latin capital letter reversed e (u+018e) There’s always a lowercase “v”. However, it usually represents the exponentiation operation. Symbol font – Unicode alternatives for Greek and special characters in HTML.

● The caret (/ ˈ k ær ɪ t /) is a V-shaped grapheme, usually inverted and sometimes extended, used in proofreading and typography to indicate that additional material … Let statement A = “All humans are mammals.” Let B = “All mammals are humans.” Let C = “Some birds can fly under some conditions.” Both ‘A’ and ‘C’ are true statements, but ‘B’ is false. In particular I would like to add an unique class to each item like. ←

Is there a special character that is the direct opposite of a caret?

In set theory, intersection and union are shown by ‘∩’ and ‘∪‘. Mike began writing professionally in 2010 as the sole proprietor of DeHaan Services. Whatever order the original developer used in the database query is what you’re stuck with. Can anyone suggest me a way to do it using any of the technologies e.g. Your email address will not be published. The “V” symbols in the reader’s question are ∨ and ∧, which mean “Logical Or” and “Logical And.” The ∧ is a capital Greek Lambda. Wolfram Mathematica Documentation. ââ
