If you’re wondering why anyone should care about making such distinctions, see this post.
#Equal sign with slash code#
Also, there is a character ħ in the Latin Extended-A portion of Unicode, U+0127 (LATIN SMALL LETTER H WITH STROKE), but the correct code point for ħ is U+210F (PLANCK CONSTANT OVER TWO PI). The correct Unicode value for h is U+210E (PLANCK CONSTANT), not simply the common h U+0068 (LATIN SMALL LETTER H). The symbol ħ is simply pronounced “h bar” and is sometimes called the reduced Planck constant. When working with angular frequency ω = 2πν, it is convenient to introduce a new constant ħ equal to h/2π so that E = ħω. In physics, Planck’s constant is the proportionality constant between energy and particle frequency: E = hν. I think the original understanding of the phrase was that if exceptions are remarkable, that shows that the rule often holds. Wikipedia says “Ш has the distinction of being the only distinctly Cyrillic letter internationally used in mathematics.” Also according to Wikipedia, sha probably comes form the modern Hebrew Shin letter (ש, U+05E9).īy the way, the phrase “the exception that proves the rule” doesn’t make sense as commonly interpreted. Sha is apparently an exception that proves the rule that Cyrillic letters are seldom used in math (at least in the West). I’d seen the Dirac comb before, but I don’t recall Ш being used as a symbol for it. The letter sha is also used in distribution theory for the “Dirac comb,” an infinite sum of evenly spaced delta functions. It is used for the Tate–Shafarevich group of an Abelian variety. Andres Caicedo pointed out that the Cyrillic letter sha (Ш, U+0428) is an exception. I mentioned in a conversation that math rarely uses Hebrew or Russian letters. The symbols ⊤ (U+22A4) and ⊥ (U+22A5) \top and \bot in LaTeX. The symbols ⊢ (U+22A2) and ⊣ (U+22A3) are \vdash and \dashv in LaTeX. x ⊣⊢ y means x and y are each provable from the other. Both expressions together are used for equivalence, i.e. Likewise x ⊣ y means that x is provable from y. The expression x ⊢ y means that y is provable from x. Logic also uses symbols that look like a T rotated 90 ° clockwise or counterclockwise, ⊢ (U+22A2) and ⊣ (U+22A3). Logic uses a symbol that looks like a sans serif T (⊤, U+22A4) to denote “true.” The same symbol turned upside down (⊥, U+22A5) is used for “false.” An advantage of using this symbol rather than some form of F is that it makes the symmetry of some formulas more apparent. The mathematical significance of the Weierstrass ℘ function is that all elliptic functions can be expressed as rational functions of this function and its derivatives. The symbol is described in Unicode as U+2118 (SCRIPT CAPITAL P). Mathematicians don’t often change the style of letters to denote special functions, but the Weierstrass ℘ function is a notable exception. The non-mathematical posts are collected here. The n-th root symbol is used to find the n-th root value of any particular number.This page contains the math-related posts from my short-lived blog Symbolism. The slash symbol is used to differentiate or to divide numbers.Ī power symbol is a special kind of symbol in which the number is multiplied several times to the value of the exponent in power.Ī decimal point is a point or period used to indicate the figures representing the units in a decimal fraction.Ī square root is a symbol that is used to calculate the root value of any number.Ĭube root is a symbol that gives the cube root value of any digit or number. Also, this bracket has to solve first if found in any equation. Parentheses is a round bracket and is used to highlight any number or character in any equation. This bracket is called the square bracket and has to solve first if present in any equation. This symbol is used to represent that the first number is either greater than or equal to the second number. This symbol is used to represent that the first number is either less than or equal to the second number. It’s used to subtract numbers and reads as minus
