The symbol is voiced -hat (or sometimes as -roof) in mathematics, but is more commonly known as the circumflex in linguistics (Bringhurst 1997, p. 274). Uses of the hat in mathematics include: 1 Typically they denote a transformed version of the base variable (e.g. $\hat{f}$ denoting the Fourier transform of $f$ as mentioned in another answer). Or, they may denote a special or specific value of a variable ($x^*$ giving the value of $x$ minimizing $f$ from another answer.

Hat is a mathematical notation used in various branches of mathematics and science. Also, the hat symbol is used in languages. In that case, the hat symbol is usually called a circumflex symbol. In latex, the hat symbol is used separately in both text and math modes As for me, in math-mode the best appearance has sequence ^\wedge. Other variants is mostly to small. - serkas Nov 3 '14 at 12:06 I have accented letters, but not the symbols ^ and ` on my keyboard The following list of mathematical symbols by subject features a selection of the most common symbols used in modern mathematical notation within formulas, grouped by mathematical topic. As it is impossible to know if a complete list existing today of all symbols used in history is a representation of all ever used in history, as this would necessitate knowing if extant records are of all. X-Bar, P-Hat and D-Bar Some codes like that for x̄ (X-bar) are actually a combination of two codes - the base letter x plus a code for the line above (&‌#772: or ̄ ). Note: These symbols use combining characters and may not appear correctly in some older browsers A common question I get (at least common in Unicode terms) is what the code is for the p-hat (p̂) symbol and x-bar (x̄) symbols in statistics. Although these are common symbols, they haven't made it as a single character into Unicode (much like there thermodynamic dot symbols are half missing unless they are also in Old Irish or another.

On the Equation Tools tab, click the Accent button in the Structures group and click the hat -- the rightmost item in the top row. hat, click Normal Text at the left end of the ribbon, and type the word. This hat has a limited width, up to three or four characters, but it may work for you There is no specific mathematical meaning to the hat symbol but it is often used to denote an estimate of the real thing, for example, if you were measuring a propagation delay you might estimate it to be half the difference between some estimated start time and some estimated end time and write it like this: t p ^ = (t e ^ − t s ^)

The hat operator is a mathematical notation with various uses in different branches of science and mathematics Definition and meaning on easycalculation math dictionary. Circumflex is a symbol used to represent a number to the power of an other number. The symbol of circumflex is ^. This symbol is also referred as Hat or Caret. Example : 2^3(ie., 2 to the power of the 3) 2^3 = 2 x 2 x 2.

If the text argument to one of the text-drawing functions (text, mtext, axis, legend) in R is an expression, the argument is interpreted as a mathematical expression and the output will be formatted according to TeX-like rules. Expressions can also be used for titles, subtitles and x- and y-axis labels (but not for axis labels on persp plots)
